Rice Lake ITCM SS Isolated Tension Cell Module - Manual (Page 3)

1. Introduction
The ITCM Weigh Module provides excellent performance in suspended tank and
hopper weighing applications. The ITCM reduces the overall assembly length to
less than half of traditional tension cell hardware arrangements and offers correct
alignment of the assembly. The combination of clevises and rod end ball joints
isolates the load cell from extraneous forces detrimental to accurate system
performance.
The ITCM incorporates an insulating system which resists the flow of stray currents
through the load cell. To insulate the load cells from the clevises, the clevises
incorporate nylon insulating washers, and the rod end ball joints are lined with
Teflon
® . A parallel grounding strap connects the two clevis assemblies to provide
an alternate path to ground, preventing load cell damage from electrical spikes or
stray currents.
The ITCM modules feature RL20000 series S-beam load cells and are available in
a variety of capacities, ranging from 100 to 20,000 pounds per module.
A single ITCM module is often used to convert a mechanical scale to electronic
operation, allowing for the added benefits of an electronic signal for process control
or data collection. When an ITCM module is inserted into the steelyard rod, the
mechanical beam or dial is still functional and can serve as a backup indicator.
The installation should be planned by a qualified structural
engineer. Each installation is unique, and this manual is
meant to serve only as a general guideline for installation.
