Weight is one of the most common measurements in industrial environments — and one of the most misunderstood. Most people treat it as a simple number on a display. In practice, weight is process data: it tells you how much material has moved, whether a batch is within tolerance, how much remains in a silo, and where losses are accumulating. Getting that data reliably requires understanding what sits at the foundation of every weighing system: the load cell. This article explains how load cells work, what types exist, and what actually determines whether a weighing system is accurate. It is the starting point. If you are already past this stage and want to know how to build a system with a specific kit, the step-by-step installation guide is here: From the Platform to the Silo: How to Build Your Own Industrial Scale.  

What a load cell does

A load cell is a sensor that converts force into an electrical signal. In industrial weighing, that force is almost always the weight of something — a product, a container, a platform, a tank full of material. The vast majority of industrial load cells work through strain gauge technology. The principle is based on a physical relationship that has been understood since the 17th century: when you apply force to an elastic material, it deforms in proportion to that force — and returns to its original shape when the force is removed. Load cells exploit this predictable deformation. Inside a load cell, a precisely machined metal element — the spring element — deforms slightly when a load is applied. Strain gauges bonded to the surface of this element change their electrical resistance in response to that deformation. These gauges are connected in a Wheatstone bridge circuit, which converts the resistance change into a small voltage signal. The signal is extremely small — typically 2 to 3 millivolts per volt of excitation voltage — but it is stable, repeatable, and proportional to the applied load. That voltage is what leaves the load cell as its output. An indicator, transmitter, or digital module receives it, amplifies it, and converts it into the weight value you read or record.  

Why the load cell is only part of the story

The most persistent misconception in industrial weighing is that measurement accuracy depends primarily on the load cell itself. It does not. In a real installation, the load cell produces a raw signal. What that signal actually represents — and how accurately it reflects the true weight — depends on everything around it. The rigidity of the structure the sensor is mounted to. Whether the load path is clean and vertical. Whether pipes, cables, or support brackets are creating parallel load paths that carry weight away from the sensors. Whether temperature changes are causing the structure to expand and contract. Whether vibration from nearby machinery is introducing noise. Most measurement errors in industrial weighing originate in the system architecture, not in the sensor. A load cell with a linearity error of less than 0.0001% — as in the H8C Rebel used in our Load Cell kits — can still produce unreliable readings if it is mounted on a surface that flexes, or if a pipe connected to a weighed tank is carrying part of the load. This is why experienced engineers think about load cells as one component in a complete measurement system, not as the primary variable. The sensor needs to be well-matched to the application, but the application also needs to be engineered so the sensor can do its job without interference.  

The main load cell types

Different designs solve different problems. The right type depends on the direction of the load, the required capacity, the mechanical constraints of the installation, and the environment. Single-point load cells are used in smaller platforms — retail scales, bench scales, compact checkweighers. Their geometry compensates for off-centre loading, meaning the weight reading does not change depending on where the load is placed on the platform. Practical for capacities up to a few hundred kilograms. Shear-beam load cells measure force through shear deformation in a horizontal beam. They are the most common type in industrial platform applications — floor scales, pallet scales, conveyor systems, and smaller tanks. Typically installed in groups of two or four. Their geometry makes them inherently resistant to side loads, which is why they hold up well in demanding environments. The H8C Rebel in the GRAM WM and GRAM MK kits is a shear-beam sensor. Bending-beam load cells work on a similar principle at lower capacities. Common in OEM machine integration and compact assemblies where space is limited. S-type load cells measure tension rather than compression. Used in suspended weighing — crane scales, hanging platforms, and force measurement rigs. Compression load cells handle very high loads — tens or hundreds of tonnes. Typical applications are vehicle weighbridges, large silos, and heavy industrial presses.  

Why shear-beam designs became the industrial standard

For most platform and process weighing applications, shear-beam sensors offer the most practical balance of performance and durability. They handle incidental side loads well. They are available across a wide capacity range. They are straightforward to install and replace. And they maintain stable readings in the kinds of environments — vibration, temperature variation, washdown — that are common in industry. No single technical property makes them dominant. It is the combination of characteristics that makes them the default choice for the widest range of applications.  

What determines whether a weighing system is accurate

Accuracy in a weighing system comes from four things working together correctly. The first is sensor quality — linearity, repeatability, temperature behaviour, and long-term stability. These are the properties specified in the datasheet. The second is mechanical installation — whether the load path is clean, the mounting surfaces are flat, and there are no parasitic connections between the weighed structure and the surrounding environment. This is where most real-world accuracy problems originate. The third is signal processing — the quality of the digital module that converts the sensor signal into a weight value. Internal resolution, filter settings, and how the module handles multi-cell inputs all affect what you read. The Xtrem digital module, for example, runs at 500,000 divisions of internal resolution and 12 samples per second, with configurable digital filters for environments with vibration or dynamic loading. The fourth is calibration — the process of telling the system what its readings correspond to in real weight units. Modern systems like the GRAM kits use factory pre-calibration (the Calready system) so you get a usable reading immediately after connection. But a span calibration using reference weights after installation accounts for the specific mechanical conditions of your setup and is recommended for any application where accuracy is critical.  

From measurement to operational data

When a weighing system is properly installed and connected to a data environment, weight stops being a local display value and becomes a continuous process signal. In batching, it enables precise dosing by weight rather than volume — more reliable for ingredients that vary in density or moisture content. In inventory management, continuous weight monitoring of tanks and silos replaces manual dip checks and supports automated replenishment. In quality control, weight is often the fastest verification that a product or package is correct. In automated lines, weight triggers the next step in a PLC sequence. In each case the load cell is the starting point. The value comes from how the measurement is integrated into the process around it.  

Where to go from here

If you are evaluating which type of load cell or system fits a specific application, the two questions that determine most of the answer are: what is the total load capacity required, and what kind of structure is being weighed — a platform or a process vessel? For platform applications up to 8,000 kg, the GRAM WM kit provides a complete solution with four H8C Rebel shear-beam cells, junction box, and Xtrem digital module. For tanks, hoppers, and silos up to 20,000 kg, the GRAM MK uses dedicated weighing modules with vibration stabilisers and anti-tip protection built in. The full installation guide — covering mounting, wiring, calibration, common mistakes, and data connectivity — is here: From the Platform to the Silo: How to Build Your Own Industrial Scale. If you are planning a specific project and want a recommendation before you start, our team can help you work through the requirements: Contact us.

The idea behind a modular load cell kit is straightforward: instead of buying a finished scale, you bring the weighing capability to whatever structure you are already working with. A steel platform, a pallet frame, a tank, a hopper, a silo — if it is rigid and bears a load, it can become a calibrated weighing system.

This guide walks through how to do that in practice, from choosing the right kit and mounting the sensors, to connecting the electronics and calibrating the system. It covers both the GRAM WM (for platforms up to 8,000 kg) and the GTAM MK (for tanks and silos up to 20,000 kg).

If you are still at the stage of understanding how load cells work and what types exist, start with our introduction: Load Cells Explained.

 

Choosing the right kit for your application

The first decision is which kit fits your application. The two systems are designed for fundamentally different installation contexts.

The GRAM WM is built around four H8C Rebel shear-beam load cells. It is designed for platforms — floor scales, pallet scales, machine bases, workbenches, or any flat rigid structure where a load sits on top. The cells mount directly to the underside of the structure using the supplied screws, and the feet below each cell make levelling straightforward. Available in capacities of 4 × 500 kg, 4 × 1,000 kg, or 4 × 2,000 kg, the system covers total weighing ranges from 2,000 kg up to 8,000 kg.

The GRAM MK uses four dedicated weighing modules designed for process installations — tanks, hoppers, and silos where the structure sits on top of the modules rather than the other way around. The modules include built-in stabilisers that compensate for vibration, and an anti-tip system for structural safety. Available in capacities of 4 × 1,000 kg, 4 × 2,500 kg, or 4 × 5,000 kg, it supports total loads up to 20,000 kg. Both nickel-plated steel and AISI 304 stainless steel versions are available for food or chemical environments.

Both kits include the same Xtrem digital module and IP67-rated stainless steel junction box, and both support cable or Wi-Fi connectivity.

 

What comes in the box

Both kits ship as complete systems. Understanding what each component does before you start makes the installation faster and avoids common wiring mistakes.

The four load cells or weighing modules are the sensors. Each one measures the portion of the total load resting on that corner. The Xtrem module combines all four readings into a single, accurate weight value.

The junction box (IP67 stainless steel, 189 × 78 × 43 mm) is where the four sensor cables meet before connecting to the Xtrem module. It handles the signal routing between cells and module. Its IP67 rating means it can be hosed down or installed in wet environments without risk.

The Xtrem digital module (140 × 67 × 33 mm) is the brain of the system. It converts the raw sensor signals into a digital weight reading, stores all calibration data internally, and handles communication to indicators, PCs, or the network. This is important: if the module is ever replaced or swapped to another installation, the calibration data goes with it.

 

Step 1: Preparing the structure

For the GRAM WM, the platform needs to be rigid, flat, and load-bearing only through the four cell mounting points. This last point is critical: if any part of the structure is resting on the floor, a wall, a pipe, or anything other than the four load cells, that contact point will carry part of the load and the measurement will be wrong. The platform must be entirely supported by the four cells — nothing else touches.

Recommended structures: welded steel frames, thick steel plate, or robust wooden platforms. Avoid anything that flexes significantly under load, as deformation in the structure introduces measurement error independent of the sensors.

For the GRAM MK, the preparation is in the foundation. The four module base plates must sit on a flat, level concrete or steel surface. Any tilt at the base transfers as a side load into the modules, reducing accuracy and potentially stressing the sensors over time. If the surface is uneven, shim or grout before installing.

In both cases, check that no pipes, cables, hoses, or guide rails are mechanically connected to the structure being weighed. Anything that creates a fixed connection between the weighed structure and the surrounding environment will carry part of the load away from the sensors.

 

Step 2: Mounting the sensors

GRAM WM Xtrem cells mount at the four corners of the platform underside. Position them symmetrically — equal distance from the edges on all sides. Use the supplied screw sets (included as a set of four for each cell). Mount on a flat surface; if the mounting surface is uneven, the cell body will be stressed before any load is applied. Tighten to contact and add a quarter turn — do not overtighten, as this preloads the sensor.

The load must act vertically downward through the cell. The H8C Rebel is a shear-beam sensor and handles incidental side loads well, but the primary load direction must be vertical. Once mounted, check that the platform sits level. The adjustable feet on the GRAM WM cells allow fine levelling at each corner.

GRAM MK modules mount differently. The tank or silo leg sits on top of the module, which sits on the foundation. Each module has defined upper and lower contact surfaces — the load path must be clean and vertical through both interfaces. Bolt the lower plate to the foundation, then place the upper saddle in contact with the structure leg. Do not weld the structure to the modules. The anti-tip cable connects the module to the structure leg and prevents tipping under eccentric loading, but it carries no weighing load — keep it loose enough that it only engages if the structure shifts.

Fit the stabilisers between adjacent modules after all four are in position. These connect the modules laterally and reduce the effect of vibration from filling, agitation, or nearby machinery on the weight reading.

 

Step 3: Wiring the junction box

Run the four sensor cables to the junction box. Each cable is labelled or identifiable by position. Connect them to the corresponding terminals inside the box following the wiring diagram included with the kit. The junction box IP67 seal must be properly closed after wiring — check that the cable glands are tightened and the lid gasket is seated correctly.

From the junction box, a single cable runs to the Xtrem digital module. Connect this to the module input. Power the Xtrem module either from 230V/50 Hz mains or at 7.5V DC — or draw power from a compatible indicator if one is connected.

For data output, the Xtrem module communicates via RS-232 as standard. Optional Wi-Fi connectivity can be added, enabling data transmission to any device on the local IP network simultaneously with the cable connection. Transmission speed is configurable from 9,600 to 115,200 baud.

Indicator compatibility note: The GRAM Z8 and GRAM Z8i Weighing Terminals and the GRAM K3 and GRAM K3i indicators are compatible with Xtrem digital equipment (both cable and Wi-Fi versions). When selecting a weighing terminal or indicator to pair with either kit, make sure it is explicitly marked as Xtrem-compatible.

 

Step 4: Calibration

Both kits use the Calready system, which means the sensors are factory-calibrated and the Xtrem module stores all calibration data. In practice, this means you can connect the system and get a meaningful weight reading immediately — without needing calibration weights on site.

However, for applications requiring verified accuracy, a conventional span calibration using reference weights is recommended after installation. This accounts for the specific mechanical conditions of your installation — the structural stiffness, the exact position of the cells, any residual preload from assembly. The Xtrem PC software and iOS/Android app (both free) include a guided calibration procedure with Adjust Zero and Adjust Span functions visible directly in the interface.

For the GRAM MK in particular, electronic calibration without weights remains possible after initial setup — useful for re-calibrating after maintenance without needing to move large reference loads to the installation site.

The Xtrem module's internal resolution is 500,000 divisions, with a speed of 12 samples per second and a linearity error below 0.0001%. External resolution depends on the capacity variant selected. The system supports up to two measurement ranges and two measurement steps, configurable via the software.

 

Step 5: Data connection and software setup

Once the system is weighing correctly, connect it to your data environment. The Xtrem module supports RS-232 and optional Wi-Fi. The free Xtrem PC software connects via cable and provides live weight display, calibration tools, and data logging. The free iOS/Android app connects via Wi-Fi and offers the same core functions for mobile access.

For integration into automation or PLC systems, the RS-232 output transmits weight data continuously at the configured baud rate. The digital module stores all calibration and adjustment parameters internally, so the data connection only carries live weight values — there is no configuration dependency on the connected system.

 

Common installation mistakes and how to avoid them

Parasitic load paths. The single most common cause of inaccurate readings is a mechanical connection between the weighed structure and something fixed — a pipe, a cable tray, a conveyor belt, or a support bracket that was left in contact during installation. Before commissioning, physically check that nothing touches the weighed structure except the four sensors.

Uneven mounting surfaces. Shear-beam cells and weighing modules both require flat mounting. A 1 mm step under a cell corner introduces a permanent mechanical offset and can cause the cell to read differently under the same load at different positions.

Overtightening mounting screws. Excessive torque on the cell mounting screws introduces mechanical stress into the sensor body before any load is applied. Follow the torque specification in the installation sheet, or tighten to contact plus a quarter turn.

Ignoring the 75–80% capacity rule. Each cell or module has a defined nominal capacity. For safe long-term operation, the total working load should not exceed 75–80% of the combined nominal capacity. For a 4 × 1,000 kg system (4,000 kg total), the practical safe working load is around 3,000–3,200 kg. Operating above this range does not necessarily cause immediate failure, but it shortens sensor life and increases non-linearity at the top of the range.

Wrong indicator model.Ensure you are using a compatible device. The GRAM Z8 and GRAM Z8i Weighing Terminals and the GRAM K3 and GRAM K3i indicators are compatible with the Xtrem digital module.

 

Sensor replacement and maintenance

One advantage of both systems is that sensors can be replaced without dismantling the entire installation. For the GRAM MK, the module design allows the sensor element to be swapped while the support structure remains in place. Since calibration data is stored in the Xtrem digital module rather than the individual sensors, replacing a faulty cell does not require a full recalibration from scratch — though a verification calibration is recommended after any sensor change.

The junction box IP67 rating means routine cleaning, including pressure washing in appropriate installations, does not require special protection of the electronics. Check cable glands and the lid gasket periodically in environments with vibration or thermal cycling.

 

What this kind of system makes possible

Once installed and connected, both kits deliver continuous digital weight data to whatever system you connect them to — PC, indicator, smartphone, or PLC. The Xtrem module supports simultaneous cable and Wi-Fi transmission, so data can go to a local display and a remote monitoring system at the same time.

For practical applications: a GRAM WM under a pallet station feeds real-time weight data to a warehouse management system. A GRAM MK under a mixing tank enables precise batching by weight rather than volume. In both cases, the kit provides the measurement infrastructure — what you do with the data depends on how you integrate it.

Industrial scales play a critical role across a wide range of industries, where precision is not just a technical requirement but a direct driver of quality, efficiency, and compliance. They are used to measure, control, and verify materials at different stages of a process—often influencing decisions that go far beyond the act of weighing itself. In manufacturing, industrial scales ensure that the correct quantities of raw materials are used, directly impacting product consistency and production reliability. In the food industry, they support accurate portioning and packaging, helping maintain product quality while avoiding overfilling or underfilling—both of which can lead to significant financial losses. In pharmaceutical applications, precise weighing is essential to guarantee correct dosages and ensure the safety and effectiveness of medications. Similarly, in the chemical industry, accurate measurement is critical for both product quality and safe handling of substances. Industrial scales also play an important role in logistics and shipping, where they help optimize load efficiency and ensure compliance with weight regulations. In the recycling sector, they contribute to material classification and value determination, supporting more efficient and transparent processes.

Basic Terms and Functions of Industrial Scales

Understanding the key features and terminology of industrial scales is essential for achieving reliable measurements and ensuring consistent performance in real-world applications. These parameters not only define how a scale operates, but also how accurately and efficiently it supports specific processes.

Capacity

This is the highest weight a scale can measure accurately. Exceeding this capacity may result in damage or inaccurate readings. An industrial scale with a maximum weighing capacity of 500 kg is ideal for medium-sized industrial products, while models with a multi-ton capacity are used in heavy industry.

Resolution

Resolution describes the fineness of the measuring steps in which the scale records and displays weight differences. The resolution indicates how precisely a scale is able to detect weight fluctuations. The value ‘d’ shows the smallest weight unit that the scale can resolve. For a scale with d = 0.1 g, the weight is displayed in increments of 0.1 g (e.g. 100.0 g, 100.1 g, 100.2 g). Practical tip: A resolution of 0.1 g is suitable for precise measurements in pharmaceuticals, while 1 kg can be sufficient for pallets in logistics.

Resolution vs. Readability

Resolution refers to the technical ability of the scale to measure and display these differences. Readability refers to the smallest difference you can see on the scale’s display.

Linearity

The ability of a scale to produce accurate measurements throughout its full range. A perfectly linear scale would have the same accuracy at any weight. Linearity is particularly important if you frequently measure different weight ranges, especially in laboratory environments where precision is critical. Good linearity ensures consistent results across the entire weighing range, whether you’re measuring minute quantities of chemicals or larger sample masses, providing the accuracy and reliability required for sensitive experiments and analyses.

Linearity vs. Reproducibility

Linearity refers to the accuracy of a scale across its entire weighing range, from the lowest to the highest capacity. It ensures that no matter the size of the object being weighed—whether it’s small or large—the scale provides a correct measurement. If a scale has good linearity, it means that it can accurately measure any weight within its range without significant deviations from the true value, ensuring consistent accuracy across different weight loads. Reproducibility refers to the consistency of the scale when weighing the same object multiple times under the same conditions. A scale with high reproducibility will give you the same result each time you measure the same object, ensuring that no random variations or external factors (like environmental conditions) affect the result.

Eccentricity

Eccentricity indicates the accuracy of a scale when the load is placed in different positions on the weighing platform. Ideally, the readings should remain consistent regardless of where the object is placed.

Calibration

Calibration is primarily done to ensure the linearity and accuracy of the scale. During calibration, the scale is adjusted so that it provides accurate readings across its entire weighing range, correcting any deviations from the true value. Calibration helps to ensure that the scale measures correctly, regardless of the weight being measured (small or large loads), which directly relates to linearity. While calibration does help with ensuring accurate measurements, it is not specifically aimed at improving reproducibility (which deals with consistency in repeated measurements) or eccentricity (which concerns accuracy when the load is placed at different points on the weighing platform). However, a well-calibrated scale can indirectly improve both by maintaining overall measurement accuracy. The value ‘c’ on an industrial scale stands for the calibration value. It indicates the smallest weight difference that is still considered reliable on a calibrated scale. With a scale with c = 1 g, weight differences of less than 1 g are not considered significant in custody transfer. The calibration value is particularly important for commercial scales that are used in business transactions. This ensures that the scale meets legal requirements.

Weighing units

Our industrial scales provide versatile weighing units including grams (g) for small measurements, kilograms (kg) for larger mass, pounds (lb) commonly used in the U.S. for weight, and ounces (oz) for lighter items, ensuring precise measurement in various applications.

Baud rate

In digital scales, this refers to the speed of data transmission between the scale and connected devices, such as computers or printers, often measured in bits per second (bps).

Maximum error

The maximum error, also known as the measurement tolerance, indicates the largest possible deviation from the actual weight that can occur in a measurement. It is an important indicator of the reliability of a scale. On a scale with a maximum error of ±0.1%, a 100kg object could be displayed as 99.9kg to 100.1kg. The maximum error is often given as a percentage of the measured weight or as an absolute value. It is particularly important in applications where precise measurements are required, such as in pharmaceuticals or food production. When selecting a scale, you should ensure that the maximum error meets the requirements of your specific application. It is important to note that in practice the actual error is often less than the stated maximum error. Regular calibrations and proper maintenance can help minimize the error and maintain the accuracy of your scale over time.

Dual-range Scales

Dual-range scales offer two different measuring ranges with different resolutions. They combine high precision for smaller weights with a large weighing range. A dual range scale could measure from 0 to 30 kg with a resolution of 10 g and from 30 to 60 kg with a resolution of 20 g. This flexibility makes dual-range scales particularly useful in applications where both small and large weights must be accurately measured, such as in food production. An example for a Dual-range Scale if our Gram Lite ZFOC.

Legal Metrology: Will you use the Scale internal or in Legal Trade?

If the scale is used internally, it may not require the stringent standards needed for trade. For trade purposes, scales must meet legal requirements for accuracy, be certified, and undergo verification. Verification ensures that the scale complies with the metrological standards set by regulatory authorities and is legally approved for commercial transactions, ensuring fair trade. Scales used in trade must be periodically re-verified to maintain compliance with these standards. Everything you need to know about scales: Verification and regulations

Industrial scales are often evaluated based on specifications—but their real value lies in how they perform within a process. Accuracy, resolution, and calibration define measurement quality. But it is their impact on consistency, efficiency, and reliability that ultimately determines their role in an operation. Choosing the right scale is therefore not just a technical decision. It is a decision that affects workflows, data quality, and long-term performance.

Laboratory balances are indispensable precision instruments for the exact measurement of weight and mass in numerous branches of industry. Since their invention in 1669 by Gilles Personne, they have evolved from mechanical scales to sophisticated digital devices with maximum accuracy and user-friendliness. They are used in the pharmaceutical industry for precise dosing and quality control, in production for component measurements and in food processing for recipe formulation and quality control. Research and development use them for chemical and biological experiments, while environmental sciences use them to analyze soil, water and air samples.

Understanding Laboratory Scales

Laboratory balances differ from conventional weighing systems through their accuracy, stability and repeatability. They are available in various capacities and resolutions — from analytical to microgram range — and can include smart functions such as automatic adjustment or data export.

Important features of laboratory balances

• High Precision: Laboratory balances offer exceptionally high measurement accuracy, down to the microgram or milligram range. This enables precise and reliable measurements for demanding applications.
• Capacity and Accuracy: Laboratory balances are available in different capacities to meet the requirements of different applications.
• Ease of use: Laboratory balances are designed to be user-friendly, with intuitive control panels and clear displays for ease of use.
• Internal automatic adjustment: Some laboratory balances, such as our Gram FV, are correctly adjusted at all times by an internal automatic adjustment system, so you can work efficiently.
• Additional functions: Many laboratory balances have additional functions such as a tare function, data storage, statistical calculations and interfaces for data transfer to a computer or printer. These functions make laboratory work easier and improve efficiency.

Types of laboratory scales

Choosing the right type of balance depends on your weighing range, accuracy requirements and environment. Here’s an overview of the most common categories

Type	Typical readability	Typical use	Example model
Analytical balance	0.1 mg	Pharmaceutical R&D, QC	GRAM FV
Precision balance	0.01–0.1 g	Production, packaging	GRAM FR, GRAM TGI
Moisture analyser	1 mg + heating	Food & chemical industries	GRAM FM
Microbalance	1 µg	Research, nanotechnology	GRAM FV
Semi-micro balance	0.01 mg	Pharmaceutical & chemical labs	GRAM FS
Density balance	0.01 g	Materials science, geology	GRAM FD
School / educational balance	0.1–1 g	Teaching & basic experiments	GRAM SPX, GRAM AC

Analytical Scales

These ultra-sensitive instruments measure very small masses with a resolution of up to 0.1 mg. Analytical balances are indispensable for pharmaceutical formulation, quality control and advanced research where precision determines product integrity. Models such as the GRAM FS and GRAM FV provide internal automatic adjustment, superior stability and intuitive operation — combining accuracy and reliability for professional lab environments.

Precision scales

Precision balances bridge the gap between analytical accuracy and industrial performance. They offer excellent repeatability, stability and speed, making them ideal for manufacturing, packaging, and laboratory applications. The GRAM FR, GRAM TG and GRAM TGI models are ideal examples — robust, versatile and designed for reliable performance in both laboratory and production settings.

Moisture analyzers

Widely used in the food, pharmaceutical and chemical industries, moisture analyzers determine the precise moisture content of a sample using controlled heating and weight-loss measurement. The GRAM FM and GRAM TH deliver repeatable, high-precision drying results, supported by programmable temperature profiles for laboratory accuracy.

Microbalances and ultra-microbalances

When measurement requirements reach the microgram level, absolute precision becomes essential. Microbalances offer readability down to 1 μg, while ultra-microbalances push the limits of modern weighing technology. The GRAM FV series includes microbalance configurations designed for controlled environments where every particle counts

Semi-microbalances

Semi-microbalances offer precision with readability of up to 0.01 mg. They are ideal for activities that require a high degree of sensitivity, but do not quite reach the required level of a microbalance, such as certain pharmaceutical applications or precise chemical experiments. The GRAM FS semi-micro version provides this perfect balance between performance and usability.

School Balances

School scales are usually simple, robust devices used in educational institutions to familiarize students with the principles of mass and weight. They can be mechanical scales such as the traditional “triple beam scale” or simpler electronic scales. Although these scales do not offer high precision, they are ideal for classroom demonstrations and elementary experiments. Models like the GRAM AC and GRAM SPX provide durability and easy operation for teaching environments.

Density Scales

Density balances are special balances that can be used to determine the density of a sample. To do this, the scales compare the weight of the sample in air with the weight of the sample when it is immersed in a liquid. This type of balance is often used in materials science labs, gemology and geology where understanding the density of a material is critical. The GRAM FD is a reliable laboratory model for density determination in both solids and liquids, ensuring fast and accurate measurement results.

 

How to choose the right Laboratory Balance

Selecting the correct laboratory scale depends on your process, environment and required accuracy. Here’s what to consider:

1. Define capacity and resolution — The smaller the samples, the finer the readability required.
2. Consider environmental stability — Analytical and microbalances need vibration-free, temperature-controlled conditions.
3. Check calibration options — Internal adjustment saves time and guarantees compliance with standards.
4. Connectivity & integration — Choose models supporting USB, RS-232, Ethernet or Wi-Fi for connection to LIMS / ERP systems.
5. Maintenance & support — Regular calibration and access to local service ensure long-term reliability.
6. Total cost of ownership — Focus not just on purchase price but on durability, uptime and service availability.

Data Connectivity in Modern Labs

Modern laboratory scales are no longer standalone instruments — data management is an essential part of efficient and traceable laboratory workflows. With our PW-Link Software, weighing results can be sent directly from the scale to our EX-Link PC software via RS-232 serial connection. From there, you can easily generate weighing reports containing key information such as the number of weighings, date, time, weight and unit. Reports can be exported in spreadsheet format for further analysis or saved as PDF files ready for printing. Each report can be personalised with your company logo and details, ensuring a professional and compliant presentation.  

Have you ever wondered how it is possible to accurately determine the water content in materials? Moisture analysers provide the answer to this question. Delve into the world of precise measurement technology and discover the many possible applications of these devices.

What is a moisture analyser?

A moisture analyser is a specialised piece of laboratory equipment designed to measure the percentage of water in materials. This technology is used in industries such as food, pharmaceutical and agriculture, where accurate moisture determination is crucial for quality assurance, consistency and product integrity.

1. Basic principle: The moisture analyser measures the loss of water in a sample by heating and monitoring the change in weight. This allows the water content to be calculated accurately.
2. Significance: Controlling moisture ensures that products such as food, pharmaceuticals and chemical materials retain their optimum consistency, shelf life and stability.

How does a moisture analyser work?

The Gram FM series uses the thermogravimetric method to determine moisture. This method relies on the instrument to heat the sample in a controlled manner and to measure the weight continuously to accurately account for the loss of moisture. Key components include:

Halogen heater:

Our Gram FM series is equipped with halogen heaters that provide even and controlled heating of the sample, which supports rapid evaporation of moisture and precise analysis.

Three heating modes

• Standard heating: In this mode, the sample is heated evenly and in a controlled manner. The temperature rises continuously and remains at the desired level, ensuring precise and stable drying. This mode is ideal for samples that require constant heating.
• Step-by-step heating: This mode heats the sample in several timed steps. Only the timer is used to adjust the heating at specific intervals. The step-by-step temperature build-up is particularly suitable for sensitive samples that require gentle drying.
• Rapid heating: In this mode, the sample is quickly heated to the desired temperature. Rapid heating enables time-saving drying and is ideal for applications where rapid moisture determination is required without damaging the sample.
• Slow heating: In this mode, the temperature of the sample is increased with a lower heating power. This gentle approach prevents moisture from evaporating too quickly, which dries the sample evenly and minimises the risk of sample changes, such as deformation or burning. The mode is particularly suitable for sensitive or heterogeneous samples that require gentle heating to achieve accurate and stable results.

The thermogravimetric method in a moisture analyzer

The thermogravimetric method in a moisture analyzer measures moisture content by recording the weight loss of a sample as it’s heated over time. This method works by placing the sample in the moisture analyzer's pan, where it is subjected to controlled heating. As the temperature rises, moisture in the sample evaporates, causing a reduction in weight. The analyzer tracks this weight change continuously until a constant weight is achieved, indicating that all moisture has been removed. The final weight loss, relative to the initial weight, is calculated to determine the moisture content of the sample accurately.

Applications of Moisture Analyzers

Moisture analyzers serve multiple industries, from quality control in food and beverage to ensuring correct formulation in pharmaceuticals and cosmetics. Key applications include:

Manufacturing thrives on precision. Whether producing automotive components, pharmaceutical products or heavy machinery, one constant remains: accurate weight measurement. Weighing systems in manufacturing are not just a control tool – they are an enabler of quality, compliance, efficiency and profitability.

This guide explores the challenges of industrial weighing in manufacturing, the features that truly matter, the most relevant scale types, and the future role of digital integration.

Why weighing matters in manufacturing

From automotive and aerospace to chemicals, food or electronics – every manufacturing process depends on precise control of raw materials, components and finished goods.

Accurate weighing ensures correct dosing and mixing, consistent quality, transparent inventory, compliance with trade and safety standards, and cost efficiency through reduced waste.

Yet maintaining precision in industrial environments is challenging. Dust, vibration, humidity or temperature changes can affect measurements. Loads range from milligrams to tonnes, and production lines demand speed, stability and legal traceability.

To stay efficient, weighing systems must deliver accuracy, durability and seamless data integration into ERP or MES systems.

Key features of manufacturing weighing systems

• Durability and load capacity: Scales must be designed for tough, continuous use. Reinforced structures and stainless steel platforms ensure long service life, even under forklift traffic or crane loads.
• Accuracy under industrial stress: Load cells and electronics must deliver precise readings despite vibration, temperature fluctuations or heavy-duty cycles.
• Speed and workflow efficiency: Fast stabilisation and user-friendly operation keep production moving. Features like tare memory, part counting or checkweighing automate routine steps.
• Connectivity and integration: Modern scales connect to ERP, MES or SPC software. Data transfer via Ethernet, Wi-Fi or cloud platforms transforms weighing into a strategic data source for process optimisation.
• Compliance and certification: Legal-for-trade verification, ISO calibration and ISOCAL certification protect against legal risks and ensure audit readiness.
• Adaptability: From bench scales for small parts to weighbridges for trucks – manufacturing requires a mix of specialised solutions, ideally with modular integration.

Modern farming is no longer guided by instinct alone – it runs on data. Among the most valuable data points is weight: how much a harvest truly yields, how efficiently feed is being used, or whether a truck leaves the farm within legal transport limits. Accurate weighing systems are therefore more than tools; they are instruments of profitability, transparency and sustainability.

This buyer’s guide provides an expert overview of agricultural weighing: the challenges farmers face, the technical features that truly matter, the solutions available on the market, and the role weighing will play in the digital farms of the future.

Weighing challenges in agriculture

Unlike other industrial environments, farms confront weighing systems with unpredictable and demanding conditions.

Handling extreme loads

Grain silos, fertiliser sacks, feed, or livestock easily exceed several tonnes. Scales must combine high load capacity with frames robust enough to withstand rough daily use and still provide reliable accuracy.

Operating in harsh environments

Dirt, mud, water and fertilisers are part of everyday farming. Without stainless steel construction and sealed load cells, weighing systems corrode quickly or deliver inconsistent results.

Need for mobility

Agricultural work is spread across barns, fields and storage sites. Farmers cannot always move loads to a central weighbridge. Mobile and modular systems save time by bringing the scale directly to the action.

Pressure for speed and efficiency

Decisions about selling produce, loading vehicles or dosing feed often have to be taken immediately. A weighing system that takes too long to stabilise or requires complex handling becomes a bottleneck.

Compliance and fair trade

For direct sales at markets or trade by weight, scales must be trade-approved. Failure to comply can mean legal consequences and loss of trust.

Key features of agricultural scales

The right weighing system combines durability, speed and intelligence. These are the features that determine whether a scale truly adds value on the farm:

Capacity and resilience in real conditions

Farm operations demand scales that can handle both high volumes and long service lives. A harvest truck arriving at the yard can weigh several tonnes, while livestock needs to be weighed repeatedly across its lifecycle. A good agricultural scale must therefore combine high load capacity with robust materials that withstand mud, impacts and constant use without drifting in accuracy.

Hygiene and resistance to contamination

In processing facilities or during produce washing, scales are exposed to water, fertiliser residues, and organic debris. Standard steel would corrode quickly, while open electronics fail under such conditions. Agricultural models with stainless steel platforms, sealed load cells and IP-rated housings are built for this reality, ensuring not only durability but also compliance with food safety and hygiene requirements.

Mobility that saves time

Farming rarely happens in one place. From weighing a grain load directly at the silo to checking livestock in a barn, mobility is a decisive factor. Portable axle pads, scales with wheels and handles, or modular beam systems make it possible to weigh at the point of action. This avoids unnecessary transport to fixed weighbridges and keeps operations running efficiently during critical harvest windows.

Fast, stable measurements even under movement

Animals rarely stand still, and harvest logistics leave no room for delays. Scales designed for agriculture use fast stabilisation algorithms and rugged load cells that can deliver reliable readings in seconds—even when the load shifts slightly. This speed is not a luxury but essential for making immediate selling or breeding decisions.

Data integration as a business tool

Modern agriculture is data-driven. Scales that can transmit results directly into farm management software, print tickets for transparent trade, or store batch information digitally transform weighing from a stand-alone task into a valuable decision-making tool. Connectivity ensures traceability, simplifies compliance, and strengthens negotiation power with buyers.

Power independence

In many barns or fields, electricity is not readily available. Agricultural scales with rechargeable batteries and low energy consumption make weighing possible anywhere, without interrupting operations or waiting for access to the nearest power source.

Suitable weighing solutions for agriculture

Different farming needs call for different weighing solutions. Below is an overview of the most common systems and where they add value.

Floor and platform scales

Large stainless-steel floor scales, such as the Gram Core Zmissil or the Gram Next Xtrem® Bengal, are indispensable for weighing harvest bags, fertiliser sacks or bulk feed. Their flat design allows easy loading with pallet trucks or forklifts, and their modular sizes fit seamlessly into barns or warehouses. For farms handling diverse product flows, they become the workhorse of daily weighing.

[show_products sku="ZMissil, 3020-1"]

Mobile vehicle weighing systems

For determining crop yields or ensuring transport compliance, portable vehicle pads like the Gram Core PR are a practical solution. They enable on-site weighing of tractors and trailers, provide both axle and gross weights, and produce printed records for transparent transactions. Especially during harvest peaks, when time is critical, this mobility eliminates the bottleneck of central weighbridges.

[show_products sku="PR"]

Beams such as the Gram Next Xtrem® Zebra can be positioned up to four metres apart, enabling farmers to weigh oversized items like water tanks, animal cages or irregular pallets. When not in use, they are easy to store—making them a versatile and space-saving option.

[show_products sku="1060"]

Veterinary scales

Accurate livestock weighing is essential for animal welfare and farm efficiency. Veterinary scales such as the Gram Core Pluto are designed for small and medium-sized animals – for example calves, lambs, pigs or goats. Thanks to their robust build and portability, they can easily be rolled into barns or fields. By weighing animals regularly, farmers can track growth, adjust feed rations and make informed breeding decisions. This not only safeguards animal health but also supports overall farm profitability

[show_products sku="1350"]

The future: weighing as a decision engine

With the integration of IoT sensors and farm management software, weighing will evolve from a measurement to a predictive tool. Scales will not only display current weights but also forecast yields, optimise feed mixtures automatically, and link data directly to sales contracts. For farms under pressure to increase efficiency and sustainability, this evolution makes weighing technology a driver of profitability and resilience.

Weighing as a lever for agricultural efficiency

Accurate, durable and connected weighing systems are more than accessories in agriculture—they are a foundation for transparent trade, efficient production and sustainable resource use. From harvest to livestock, every precise measurement strengthens decision-making and secures profitability.

By investing in the right scale today, farms position themselves to meet tomorrow’s challenges with data, efficiency and confidence.

Choosing the right material for an industrial scale is more than a technical detail – it determines how long the equipment will perform reliably under real working conditions. Moisture, aggressive cleaning agents, and chemical exposure are daily realities in industries such as food processing, pharma, and logistics. If the wrong steel is used, corrosion, hygiene issues, and premature failures are inevitable.

Industrial scales are typically built from three types of material:

• Epoxy-coated steel – a carbon or alloy steel base protected by an epoxy resin layer. Affordable and sufficient for standard environments, but vulnerable once the coating is scratched or worn.
• AISI 304 stainless steel – an austenitic chromium-nickel alloy with good corrosion resistance, widely used in general-purpose applications.
• AISI 316 stainless steel – enriched with molybdenum, designed to resist chlorides, salts, and aggressive chemicals, making it the benchmark for waterproof and hygienic scales.

Epoxy-Coated Steel vs. AISI Stainless

Epoxy coatings provide a first line of defense but depend on surface integrity. In dry storage areas or basic logistics, this is often sufficient. However, once cracks, scratches, or chemical stress compromise the coating, the underlying steel is exposed and corrosion starts rapidly.

AISI stainless steels solve this differently: their resistance is built into the material itself. Even if the surface is damaged, the passive chromium oxide layer renews itself, ensuring long-term protection. This makes them far more reliable for scales that undergo daily washdowns, exposure to salts, or chemical cleaning routines.

What Does AISI Mean in Steel?

AISI stands for American Iron and Steel Institute. The system classifies steels by their chemical composition and properties. In particular, stainless steels have become internationally standardized under AISI – alongside European systems such as DIN and EN.

The most common series include:

• AISI 200 series: Austenitic chromium-nickel-manganese steels
• AISI 300 series: Austenitic chromium-nickel steels (304, 316, etc.)
• AISI 400 series: Ferritic and martensitic steels

For industrial scales, the most relevant grades are 304 and 316 from the 300 series.

Why the Steel Grade Matters for Waterproof Scales

Waterproof industrial scales are used wherever regular cleaning, high humidity, or exposure to aggressive substances is part of daily operations. Typical industries include:

• Food processing: meat, dairy, bakeries
• Pharma: sensitive production environments with strict hygiene standards
• Chemicals & logistics: harsh cleaners, outdoor use, or salt-rich air

The three key requirements are:

1. Corrosion resistance → protection against water, salt, and cleaning agents
2. Hygiene → smooth, easy-to-clean surfaces without material degradation
3. Durability → resistance to abrasion, temperature fluctuations, and chemicals

Choosing the wrong steel results in rust, reduced lifespan, and costly downtime

Comparison of the Most Relevant AISI Grades for Industrial Scales

AISI Grade	Properties	Advantages	Typical Applications
AISI 304	Chromium-nickel steel, good corrosion resistance	Cost-effective, versatile, hygienic	Standard scales for kitchens, labs, and retail
AISI 316	Chromium-nickel-molybdenum steel, high chloride resistance	Excellent in wet, salty, or chemical environments	Waterproof scales in food & chemical industries
AISI 316L	Low-carbon version of 316	Less prone to intergranular corrosion, better weldability	Precision scales, pharma, medical technology
AISI 430	Ferritic chromium steel, lower cost	Magnetic, more corrosion-resistant than carbon steel but weaker than 304/316	Basic scales without heavy cleaning
AISI 904L	Highly alloyed with nickel & molybdenum	Outstanding resistance to acids and aggressive chemicals	Specialized scales for extreme conditions

AISI 304 vs. AISI 316: The Classic Comparison

• AISI 304: The reliable all-rounder. Best for environments that require hygiene but are not subject to extreme chemical or salt exposure – such as labs or dry food areas.
• AISI 316: The premium choice for wet, salty, or chemically aggressive environments. Thanks to its molybdenum content, it resists chlorides and harsh cleaning agents, making it the go-to option for meat processing, dairies, outdoor logistics, and chemical plants.

👉 In short:

• 304 = versatile & cost-efficient
• 316 = best choice for water, salt, and chemical exposure

Practical Use Cases

• Meat processing: Daily high-pressure cleaning with chlorine-rich detergents – only AISI 316 withstands this long-term.
• Outdoor logistics: Platform scales in coastal warehouses or harbors → AISI 316 is essential, as salty air corrodes 304.
• Laboratories & pharma: AISI 304 is often sufficient – hygienic, easy to clean, and cost-effective.

The choice of the right AISI grade has a decisive impact on the performance and service life of waterproof industrial scales. AISI 304 works as a versatile solution for standard environments, while AISI 316 offers the premium option whenever moisture, salt, or chemicals are involved. For highly demanding conditions, special alloys like 316L or 904L provide maximum safety even under extreme stress.

By selecting the appropriate AISI stainless steel, you ensure long-term measurement accuracy, compliance with hygiene standards, and minimized downtime.

By selecting the appropriate AISI stainless steel, you ensure long-term measurement accuracy, compliance with hygiene standards, and minimized downtime.

 

IP Classification (International Protection) is an internationally standardized system that indicates how well an electrical device is protected against the intrusion of foreign bodies (dust, dirt) and moisture (water, steam, jet water).

The IP code always consists of two digits:

• First digit: Protection against solid foreign objects and dust
• Second digit: Protection against moisture and water

Example: IP-65 means dust-tight and protected against water jets from all directions.

IP Protection Table at a Glance

First digit – Protection against contact & foreign bodies

Digit	Protection against contact	Protection against solid foreign objects
0	No protection	No protection
1	Protected against large-area contact (e.g. back of the hand)	Protected from objects ≥ 50 mm in diameter
2	Protected against contact with a finger	Protected from objects ≥ 12.5 mm (e.g. screws, nuts)
3	Protected against access with tools or wires ≥ 2.5 mm	Protected from objects ≥ 2.5 mm (e.g. thick wire scraps, shavings)
4	Protected against access with tools or wires ≥ 1 mm	Protected from objects ≥ 1 mm (e.g. fine dirt, dust particles)
5	Complete contact protection	Dust-protected – ingress only in harmless amounts
6	Complete contact protection	Dust-tight – no dust ingress possible

Second digit – Protection against water

Digit	Protection against water
0	No protection
1	Protected against vertically falling water drops
2	Protected against water drops falling at an angle (up to 15°)
3	Protected against spraying water up to 60° from vertical
4	Protected against splashing water from all directions
5	Protected against water jets from a nozzle
6	Protected against strong water jets (e.g. high pressure)
7	Protected against temporary immersion (up to 1 m for max. 30 min.)
8	Protected against continuous immersion
9K	Protected against high-pressure and steam jet cleaning

Together, both digits define the specific IP classification. Example: IP-67 = dust-tight + protected against temporary immersion in water.

Why IP Classification Matters for Industrial Scales

In industrial environments, scales must deliver reliable and precise results—even when exposed to dust, humidity, or cleaning processes. This is where IP classification becomes essential.

The most sensitive components are:

• Load cells – the core of any scale. Even minimal moisture or corrosion can distort measurement results.
• Junction box: Connects the load cells to the electronics. Without IP protection, it is the first weak point exposed to dust or water.
• Display & electronics: Dust particles, splashing water, or high-pressure cleaning can quickly lead to failures if not adequately protected.

The right IP class ensures that scales measure precisely, last longer, and require less maintenance.

Common IP Protection Types for Industrial Scales

In practice, specific IP classes have proven particularly relevant for industrial scales:

IP Class	Protection against dust/solids	Protection against water	Typical applications
IP-54	Dust-protected (limited ingress allowed)	Protected against splashing water	Logistics, dry industrial environments
IP-65	Dust-tight	Protected against water jets	Food industry, production areas with wet cleaning
IP-67	Dust-tight	Protected against temporary immersion (up to 1 m, 30 min.)	Fish industry, meat processing, outdoor use
IP-68	Dust-tight	Protected against continuous immersion	Chemical industry, extreme moisture environments

Important: “Waterproof” does not always mean the same thing.

• IP-65 only protects against water jets.
• IP-67 withstands short immersion.
• IP-68 allows continuous underwater use.

Especially in the food and chemical industries, these differences are crucial.

Benefits of Choosing the Right IP Classification

Selecting the right IP class provides not only technical protection but also tangible business advantages:

• Longer lifespan: Scales that are protected against dust and moisture operate reliably for many years. Corrosion and wear on load cells or electronics are significantly reduced.
• High accuracy: If dust or water cannot reach internal components, measurement remains precise. This is critical in industries where even small deviations translate into high costs.
• Lower maintenance costs: Well-protected scales experience fewer breakdowns. This saves repair expenses and minimizes downtime in production.
• Increased operational safety: Faulty measurements or failures can disrupt entire processes. The right IP class reduces these risks and ensures smooth operations.

Maintenance and IP Protection: What Really Matters

The IP classification of an industrial scale is a fixed specification and does not change through use. A scale with IP-65 will always remain IP-65 according to the standard.

However, the actual protective performance can decrease over time—for example due to:

• brittle or damaged seals,
• loosened housing screws,
• improperly closed cable glands or junction boxes,
• aggressive cleaning agents that attack materials.

Regular maintenance helps ensure long-term protection. This includes:

• inspecting and replacing seals when necessary,
• checking all connection points,
• adapting cleaning routines to extend the scale’s service life.

This way, the scale remains as well protected in practice as its IP rating promises—and continues to deliver consistently precise results.

The Right IP Classification for Reliable Industrial Scales

IP classification is far more than a technical label—it determines whether an industrial scale will perform reliably under real-world conditions. Whether it’s dust in production, water jets in food processing, or constant moisture in chemical environments: only when scales, load cells, and junction boxes are properly protected will measurements remain accurate and your investment pay off in the long term.

Our tip: When selecting a scale, don’t just focus on capacity and features. Always make sure the IP rating matches your environment to guarantee long-lasting, reliable performance.

In the food processing industry, and in meat processing in particular, hygiene and food safety are of the utmost importance. Every phase of the production process must adhere to the strictest standards to avoid contamination and protect the health of consumers. A central component of these processes are special waterproof scales that enable precise and reliable weighing while maintaining strict hygiene standards.

The Food Processing Industry in the European Union

The food and drink industry is the largest manufacturing sector in the European Union, generating a turnover of €1.2 trillion, employing 4.7 million people, and contributing €250 billion in value added annually. It plays a vital role in the EU economy: in half of the EU Member States, it is the largest industrial employer. In 2025, the European food market is expected to reach a volume of 493 billion kilograms, which corresponds to an average of 530 kg per person. With US$2.14 trillion in revenue forecast for 2025 and a trade surplus of €80 billion, the EU is the world’s largest exporter of food and drink products—65% of exports remain within the Single Market, while €182 billion are exported outside the EU. Complementary figures from the European Commission’s Agri-Food Data Portal also provide detailed insights into production volumes and usage across all Member States.

Facts and figures about the food processing industry in the European Union:

• Regulatory Framework: Food producers in the EU must comply with stringent hygiene and food safety regulations, including Regulation (EC) No 178/2002, the Food Hygiene Regulation (EC) No 852/2004, and Food Information Regulation (EU) No 1169/2011. These ensure safe food, transparent labeling, and full traceability across the supply chain.
• Green and Digital Transition: In March 2024, the European Commission launched the Transition Pathway for the Agri-Food Industrial Ecosystem, outlining specific actions to support the sector’s green and digital transformation. This includes promoting energy efficiency, automation, and resilient production — areas where washdown-ready, smart weighing systems play a vital role.
• Export and Internal Market: The EU is a net exporter of food and drink products, with over €182 billion in exports and a positive trade balance of almost €30 billion. Around 60% of exports go to other EU countries, reflecting the strength of the Single Market. Scales used in this environment must meet high operational and legal standards to ensure fair trade, accurate labeling, and cross-border compliance.

Why are waterproof industrial scales important for food safety?

In food processing, all equipment that comes into contact with food must meet the highest hygiene requirements. This applies in particular to scales that are in direct contact with raw materials and products. In particular, washdown industrial scales contribute to food safety by enabling the following:

Preventing contamination

Bacteria and other micro-organisms can accumulate in the cracks and crevices of equipment. Waterproof scales with smooth, stainless steel surfaces and sealed joints eliminate gaps where food particles or moisture could accumulate, significantly reducing the risk of cross-contamination.

Accurate Weighing in Humid Conditions

Moisture and condensation can affect the accuracy of regular scales. Waterproof models, however, are designed with hermetically sealed load cells that provide consistent accuracy, even in the most challenging environments.

Comply with legal health and safety requirements and ensure quality for consumers

In the EU, there are strict hygiene regulations that food companies must comply with. Our waterproof scales are designed to meet legal standards so that companies can pass their tests without any problems. For consumers, strict hygiene in food production means a lower risk of contamination and health risks from food.

• Regulation (EC) No 178/2002 – General Food Law: This regulation forms the foundation of EU food law. It lays down the principles and requirements for food safety, including the traceability of food and requirements for dealing with unsafe food. Businesses must ensure that food is safe and suitable for human consumption.
• HACCP (Hazard Analysis and Critical Control Points): According to EU Regulation (EC) No. 852/2004 on food hygiene, food companies are obliged to implement an HACCP system. This system is designed to identify, evaluate and control potential hazards for food safety. As part of an HACCP system, washdown scales can help to monitor critical control points in processing and packaging.
• European Food Information Regulation (FIR) No. 1169/2011 – labelling of food: This regulation concerns the requirements for the labelling of food and ensures that consumers are fully informed. Precise scales such as washdown scales play a role here, as exact weight information is required on the packaging.

Features of washdown scales for the food industry

• Hygiene and cleanability: Systems made of materials such as stainless steel are preferable for easy cleaning and disinfection.
• Resistance to water and dust: Given the wet and particulate nature of meat processing, equipment with high IP ratings for water and particle resistance is essential. Equally important is choosing a suitable steel grade so that all surfaces can resist moisture, bacteria and cleaning chemicals.
• Overload protection: Overload protection mechanisms, such as the limit function, protect the scale from damage due to excessive weight, thus preventing inaccuracies and potential safety hazards.

The main types of industrial weighing systems for food plants

Platform Scales

Platform scales that can be mounted in a pit are the most versatile and durable choice for food processing and especially for meat processing plants. They can easily handle heavy loads of up to 2,000+ kilograms while also being corrosion and bacteria resistant.

Bench Scales

Stainless steel bench scales are ideal for manually weighing smaller items or portions. Look for seamless surfaces, bevelled fronts and durable load cells.

Pallet Scales

Pallet scales allow you to weigh full pallet loads directly at the production line – reducing transport steps and improving workflow.

Pallet truck Scale

Pallet truck scales or pallet jacks combine transport and weighing in one device – ideal for lean production environments where speed and space efficiency matter.
