The Bently NevadatM 3500/70M Recip Impulse Velocity Monitoris a 4-channel device used as part of the reciprocatingcompressor solutions package to monitor compressorcrankcase and crosshead vibration. The monitor acceptsinput from seismic transducers, conditions the signal toderive vibration measurements, and compares theconditioned signals with user-programmable alarms.You can program each channel using the 3500 RackConfiguration Software to perform the following functions:
Impulse Acceleration
Acceleration 2
Recip Velocity
Low Frequency Recip Velocity
