Choosing the Correct Weigh Module
The wide variety of weigh modules available can make it challenging to determine the differences and what system is best for your application. Most weigh module uses can be classified into one of three categories:
· Suspended Weighing · Vessel Weighing · Truck Scale Weighing
Complete Mounting Kits
Complete mounting kits are available with our weigh modules, simplifying the selection and installation processes. Each kit comes with a detailed installation manual and an analog junction box with cable assembly, eliminating the need to order separate parts. All standard weigh module kits include the required load cell(s), junction box, mounting hardware and cable, but can be customized to meet your exact needs.

Suspended weigh modules support load cells that are hung vertically and measure through tension, such as in suspended hoppers. Suspended weigh modules are available in stainless or mild steel.
ITCM Series (Isolated Tension Cell Modules)
Featuring a clevis and rod-end ball-joint assembly, the ITCM mount is half the overall length of traditional s-beam tension mounts. This unique design consistently corrects loading alignment, even in difficult applications. The load cell is completely isolated from stray currents using PTFE-lined rod ends and a grounding strap which provides an alternative path to ground. Use in single- or multiple-module configurations. Most capacities are NTEP approved.
