Bently Nevada 3500/70M Recip Impulse Velocity Monitor

The Bently Nevada 3500/70M Recip Impulse Velocity Monitor is a 4-channel device used as part of the reciprocating compressor solutions package to monitor compressor crankcase and crosshead vibration. The monitor accepts input from seismic transducers, conditions the signal to derive vibration measurements, and compares the conditioned signals with user-programmable alarms.

You can program each channel using the 3500 Rack Configuration Software to perform the following functions:

Impulse acceleration
Acceleration 2
Recip velocity
Low frequency recip velocity
