The Bently Nevada 3500/77M Cylinder Pressure Monitor is a 4-channel monitor that accepts input from Bently Nevada approved pressure transducers, conditions the signal to make various pressure measurements for reciprocating compressors, and compares the conditioned signals with user-programmable alarms. The 3500/77M provides:

  • Machinery protection by continuously comparing monitored parameters against configured alarm setpoints to drive alarms
  • Essential machine information for operations and maintenance personnel

Each channel of the 3500/77M will provide eight measured variable values that relate to cylinder pressure operation. The five values that relate to a single chamber are as follows:

  • Discharge Pressure
  • Suction Pressure
  • Maximum Pressure
  • Minimum Pressure
  • Compression Ratio
