Product details

3500/77M reciprocating pulse speed monitor

summarize

The 3500/77M Reciprocating Pulse Speed Monitor is a four-channel device used as part of the reciprocating compressor solution package to monitor compressor crankcase and crosshead vibration. The monitor receives input from seismic sensors, processes the signal to derive vibration measurements, and compares the processed signal to a user-preset alarm threshold.

Programming and function

You can program each channel using 3500 rack configuration software to perform the following functions:

Pulse acceleration

Acceleration 2

Reciprocating speed

Low frequency reciprocating velocity

The main purpose of the 3500/77M reciprocating pulse speed monitor is to:

Provide mechanical protection for reciprocating compressors to drive alarms by continuously comparing monitoring parameters with configured alarm thresholds

Provides important machine information on reciprocating compressors to operators and maintenance personnel

Input signal processing and alarm setting

Each channel, depending on the configuration, typically processes the input signal to generate various parameters called static values. You can configure a warning threshold for the static value of each activity and a danger threshold for the static value of any two activities.

Sum up

The 3500/77M reciprocating pulse speed monitor with its four-channel design, flexible programming function and powerful vibration monitoring capability provides a strong guarantee for the safe operation of reciprocating compressors. Whether it is used to monitor compressor status in real time or to provide critical information to operations and maintenance personnel, the monitor plays a key role in ensuring efficient and stable operation of the compressor.
