IO973 6 channel strain gauge simulator

IO972/IO973: 6 channel strain gauge simulator module

6 channel strain gauge simulator modules that simulates the operation of a range of strain gauges, with Simulink driver blocks

The IO972 and IO973 product series are strain gauge simulator modules with 6 channels. They provide a simple way of replacing in-house developed sensors with low-cost simulators using the same resistor bridge techniques that real-life strain gauges are based on. Each strain gauge simulator channel includes an independent input for the Excitation Voltage and a bridge output to simulate a strain gauge. The Excitation Voltage port can be driven by an AC or a DC source. The bridge circuit includes three fixed resistors and a fourth programmable resistor that can be adjusted. The standard bridges are 350Ω, 1kΩ, 2kΩ or 3kΩ. Other resistance models can be provided on request.
