3B20 - AC Strain Gage

Description

The 3B20 is a wideband single-channel signal-conditioning module which interfaces 4-arm AC bridge transducer signals ranging between 1.5mV rms and 150mV rms, providing simultaneous precision voltage and current outputs.

Features

  • Interfaces, amplifies, & filters signals from 4-arm AC bridge transducer signals ranging between 1.5mV rms & 150mV rms. Module provides an AC excitation voltage of 2V rms to 10V rms at frequencies between 1kHz & 10kHz. . Module provides simultaneous precision voltage and current outputs. Module circuitry can withstand 130v rms at its current output terminals without damage. All 3B20 series modules are mix-and-match and Hot Swappable.
