Mini-amplifier [ 90376 ]

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