System and Load Cell Tests
Overview of Typical Load Cell System
The typical system consists of one or more load cells/points, a summing junction box, and
an HI 6500 Weight Processor.
Load sensor
- Used to measure pressure, weight, or torque, the sensor is a strain gauge-
based force transducer that generates an electrical signal proportional to the load applied.
This can be done using either tension or compression type load sensors. When the HI 6500
sends the load cell a 5-volt DC excitation signal that powers the load cell, the force
transducer generates a millivolt output proportional to the load (0-10mv DC for 2mv/V load
cells/ points or 0-15mv DC for 3mv/V load sensor).
Weight Processor
- This is part of the HI 6500 that, among other functions, powers the load
cell(s)/point(s), receives the millivolt signal output from the load cell(s)/point(s), and
digitizes, interprets, communicates and displays the results.
