A low-cost signal conditioner designed to work with bridge-type transducers and PowerLab data acquisition systems. The Bridge Pod provides a stable +2.5 V excitation source for full-bridge strain-gauge transducers. A 300 Hz low-pass filter is built-in to reduce signal noise and a manual DC offset adjustment is provided.

For use with:

Key Features

  • An excitation voltage of 2.5 V applied to the transducer with the transducer output signal being differentially amplified and then low pass filtered to remove high frequency signals.
  • Offset adjustment by a 10-turn potentiometer on the front of the Bridge Pod, allowing transducer offsets or pretension load signals to be removed before recording.
  • Offset control provides ±200 mV of offset range (at input) on the low gain setting and ±20 mV of offset range (at input) on the high gain setting.
