Bently Nevada 3500/70M Recip Impulse Velocity Monitor
The Bently Nevada 3500/70M Recip Impulse Velocity Monitor is a four-channel device that monitors crankcase and crosshead vibration in reciprocating compressors. It accepts seismic transducer inputs, conditions the signals, compares them with user-programmable alarm setpoints, and can be configured via the 3500 Rack Configuration Software to measure impulse acceleration, acceleration 2, reciprocating velocity, or low-frequency reciprocating velocity for reliable compressor protection.
