Functional Description

Bently Nevada 3500/70M Recip Impulse Velocity Monitor is a 4-channel device used as part of the reciprocating compressor solutions package to monitor compressor crankcase and crosshead vibration. The monitor accepts input from seismic transducers, conditions the signal 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:
1. Impulse Acceleration
2. Acceleration 2
3. Recip Velocity
4. Low Frequency Recip Velocity
The monitor channels are programmed in pairs and can perform up to two of the aforementioned functions at a time. For example, channels 1 and 2 can perform one function while channels 3 and 4 perform another or the same function.
The primary purpose of the 3500/70M Recip Impulse Velocity Monitor is to provide the following:
1. Machinery protection for reciprocating compressors by continuously comparing monitored parameters against configured alarm setpoints to drive alarms
2. Essential reciprocating compressor machine information for both operations and maintenance personnel
Each channel, depending on configuration, typically conditions its input signal to generate various parameters called static values. You can configure alert setpoints for each active static value and danger setpoints for any two of the active static values.
