Bridge Amplifier

This miniature, on-board, transducer amplifier is capable of supplying excitation voltage and amplifying millivolt signals from strain gauge based transducers.

The model 90376 bi-polar amplifier can be mounted inside the housings of many of our load cells and torque sensors. Where space is a premium, these amplifiers can also be integrated into the back shell of the connector, or in-line with the signal cable. Uses include interfacing sensors with PC cards, A/D boards, standard panel meters, and other instrumentation that require high-level analog signal inputs.

Model number: 90376
