The 8065 vibration module is designed to power and accept an AC signal from a constant-current accelerometer. The module integrates this signal and provides a 0-10V output proportional to RMS velocity and enveloped g output plus a buffered, unfiltered (raw AC) output for connection to a data collector. The module can operate with any 2-wire constant-current accelerometer i.e. 1100, 1120, 1130, 1830, 1135 etc. Envelope g values are considered by many to be a sensitive and convenient marker for bearing wear.
