BENTLY NEVADA 176449-09 3500/70M Recip Impulse Velocity Monitor

The BENTLY NEVADA 176449-09 3500/70M Recip Impulse Velocity Monitor is a 4-channel device for monitoring compressor crankcase and crosshead vibration in reciprocating compressors. It accepts input from seismic transducers, conditions signals for vibration measurements, and compares them to user-set alarms.

Each channel can be programmed using the 3500 Rack Configuration Software for functions like Impulse Acceleration, Acceleration 2, Recip Velocity, and Low-Frequency Recip Velocity. Channels are grouped in pairs, allowing them to perform different or similar functions.

The main purposes of the 3500/70M Recip Impulse Velocity Monitor are:

1. Machinery protection by continuously comparing parameters to configured alarms.
2. Providing essential information for compressor operations and maintenance.

Each channel generates static values based on its input, and you can set alert and danger thresholds for these values.
