143729-01 Bently Nevada, 3500/77M, Cylinder Pressure I/O Module

Description:

143729-01 Cylinder Pressure I/O Module with Internal Terminations for Bently Approved Third Party Pressure Transducers.

The 3500/77M Recip 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 primary purpose of the 3500/77M monitor is to provide:
• Machinery protection by continuously comparing monitored parameters against configured alarm setpoints to drive alarms.
• Essential machine information for operations and maintenance personnel.
Depending on configuration, each channel typically conditions its input signal to provide various parameters called measured variables. Users can configure Alert setpoints for each active measured variable and Danger setpoints for any two of the active measured variables. 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
Three measured variables combine one or more channel values with configured mechanical parameters to compute their value:
• Peak Rod Compression
• Peak Rod Tension
• Degree of Rod Reversal

Frequently Asked Questions:
