Signal Conditioner

Model 90131 Bridge sensor is a self-contained, AC powered, signal conditioning module for bridge type sensors. It contains a precision differential instrumentation amplifier with filtered output and a highly regulated low noise, adjustable output bridge excitation source. The unit is completely encapsulated for use in rugged environments. The output filter cutoff frequency is 200 Hz and may be lowered by adding two external capacitors.

Model number: 90131
