This is an amplifier to convert a Wheatstone bridge load cell signal to a 0-5V analog signal. Designed for 3mV/V load cells but will work with less sensitive cells, with less resolution.

What sets this one apart from most of the general purpose load cell amplifiers is it's designed for 5V operating voltage so it can run off the ECU 5V supply for maximum precision (no offset errors as a result from running the load cell at a different voltage than the analog-digital converter) and there is only one potentiometer for adjusting zero offset voltage, the gain is fixed for reliability.

Typical use case is dynamometer torque measurement.
