Indicators & Terminals
Works seamlessly with GRAM’s Xtrem indicator family — K3X, K3iX, K3iX-P, K3W, K3iW — as well as the Z8 and Z8i weighing terminals.
All models connect digitally via ZLink® (cable or Wi-Fi) and offer features such as 3-colour checkweighing, zero tracking for tanks and silos, totalisation, 20 tare memories, and robust IP65 protection with stainless steel or ABS housings.
Platform Accessories
Stainless-steel ramps make access with manual pallet trucks faster and safer. Stainless pit frames with perimeter plates and centring plates allow fully recessed floor installation, while stainless transport guides let you move the platform securely with a forklift. ZLink® connection cable in 4.5 m (standard), 8 m or 15 m adapts easily to your layout.
Printers
Compatible with PR4 and Q2 printers for fast, reliable ticket or label printing via cable from K3 indicators. The Q1 Bluetooth label printer adds mobile printing from the XTREM Android app, with barcodes, long autonomy and wireless operation around the platform.
Software & Apps
EX Link and PW Link PC applications handle data capture, visualisation and CSV export. PC Xtrem software turns the PC into a CE-M verified indicator with high-resolution display and multi-scale management, while the XTREM Android app enables Wi-Fi connectivity, label printing, advanced traceability and Excel export. USB output options ensure smooth integration with your IT systems.
Visual Signals & Remote Displays
An LED traffic light with relay board provides three adjustable levels for product classification or weight-difference alarms. The RD3 wall-mounted repeater display mirrors the K3 indicators with large 80 mm digits, so operators see weight clearly from a distance.
Supports, Columns & Calibration
Stable painted or stainless-steel bases with 900 mm columns (CS1 / CS1S) and dedicated wall brackets — U-shaped or ball-joint — allow ergonomic installation of K3 indicators. Xtrem equipment is supplied with CE-M Verification as standard, and optional ISOCAL Certificates with individual calibration data help maintain ISO 9001-compliant quality systems.
