Bently Nevada 3500/70M 136449-09 Reciprocating Impulse Velocity Monitor

Bently Nevada 3500/70M 136449-09 Reciprocating Impulse Velocity Monitor

Product Description

• Manufacturer: Bently Nevada
• Product Type: 3500/70M Reciprocating Impulse Velocity Monitor
• Function: A 4-channel device used in the reciprocating compressor solutions package 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.
• Primary Purpose: Machinery protection for reciprocating compressors by continuously comparing monitored parameters against configured alarm setpoints to drive alarms. Provides essential machine information for operations and maintenance personnel.
