  Low frequency reciprocating speed

  The 3500/70M reciprocating pulse velocity monitor is a 4-channel device used as part of the reciprocating compressor solution package to monitor compressor crankcase and crosshead vibration.The monitor receives input from the seismic transmitter,adjusts the signal to obtain vibration measurement values,and compares the adjusted signal with user programmable alarms.

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

  Pulse acceleration

  L acceleration 2l reciprocating speed

  Low frequency reciprocating speed

  The monitor channels are programmed in pairs and can perform up to two of the above 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 main purpose of the 3500/70M reciprocating pulse speed monitor is to provide the following functions:

  Drive alarms by continuously comparing monitored parameters and configured alarm setpoints,thereby providing mechanical protection for reciprocating compressors.

  Basic mechanical information of reciprocating compressors provided for operation and maintenance personnel

  According to the configuration,each channel typically adjusts its input signal to generate various parameterized static values.You can configure alert setpoints for each activity static value and set danger setpoints for any two activity static values.

  application area

  The 3500/70M BENTLY pulse velocity monitoring system is widely used in industries such as oil and gas,power generation,manufacturing,and transportation,where the performance and reliability of rotating machinery are crucial.It helps engineers and maintenance personnel monitor and identify potential issues in the machine,enabling proactive maintenance and minimizing downtime.
