Bently Nevada 3500/70M Recip Impulse Velocity Monitor

Description

Product DescriptionThe 3500/70M Recip Impulse Velocity Monitor is a 4-channel device used in reciprocating compressor solutions to monitor compressor crankcase and crosshead vibration. It accepts input from seismic transducers, conditions the signals 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
