Indicators & Terminals

GRAM WM integrates seamlessly with GRAM’s digital indicators — K3X, K3iX, K3W, K3iW — as well as the Z8 and Z8i weighing terminals, via cable or optional Wi-Fi.
All compatible models support high-resolution weighing, 3-colour checkweighing, multi-tare management, totalisation, and fast response times, powered by the Xtrem® module, which securely stores all calibration and adjustment data within the system.

Printers

Through its K3-series indicator compatibility, GRAM WM works with GRAM’s PR4 compact thermal printer and the Q2 label/ticket printer, ensuring reliable documentation and clear traceability across industrial workflows.

Connectivity, Software & Data integration

GRAM WM includes RS-232C connectivity as standard and offers Wi-Fi as an optional module, allowing the system to transmit data simultaneously via cable and wireless, which shows both paths operating in parallel. The integrated Xtrem® digital core ensures secure, stable communication and enables direct data transfer to PCs, tablets or Android smartphones, without requiring an indicator. Through a Wi-Fi network, the system can communicate with any equipment connected to the same IP infrastructure, while the Xtrem module protects all critical calibration and adjustment parameters internally.

The kit works harmoniously with Xtrem PC Software for PC-based indication, EX Link for data capture and record import, PW Link for real-time display and CSV export, and the Xtrem App for Android, which supports multi-terminal workflows and advanced traceability functions.

Mounting, Cables & Accessories

GRAM WM is compatible with GRAM’s full installation ecosystem, including painted and stainless-steel bases with 900 mm indicator columns, stainless U-brackets, wall-mount systems and ABS swivel supports. Connectivity options include RS-232 cables for RD3, printers or PCs, Direct K USB, standard USB outputs, Wi-Fi boards and digital expansion accessories such as the 3-relay board and RTC board. These components allow the system to adapt to a wide range of industrial integration requirements.

Remote displays & Visual signals

The kit supports the RD3 repeater display, which provides high-visibility weight information in remote or elevated positions. It is also compatible with the three-level LED traffic light, offering immediate colour-coded feedback for checkweighing, classification and process control.

Certification & Calibration

Optionally available with ISOCAL certificates.
These provide individual calibration data and full traceability to support quality systems in accordance with ISO 9001.
