Analog Devices 3B20 AC Strain Gage Torque Transducer Input Datasheet
The Analog Devices 3B20 is a wideband, single-channel signal-conditioning module designed to interface with 4-arm AC bridge transducer signals ranging from 1.5mV rms to 150mV rms. It provides simultaneous precision voltage and current outputs and includes an AC excitation voltage capability of 2V rms to 10V rms at frequencies between 1kHz and 10kHz. The module is part of the 3B Series Signal Conditioning I/O Subsystems, which are mix-and-match and hot-swappable for industrial signal conditioning, isolation, and filtering applications.
