Overview
The Bently Nevada 3500/77M Cylinder Pressure Monitor (P/N: 140734-07) is a 4-channel device engineered for high-precision monitoring of reciprocating compressors. It accepts inputs from Bently Nevada-approved pressure transducers and converts them into actionable cylinder pressure measurements. The system enables real-time monitoring, alarm management, and operational insights for maintenance and process optimization.
Key Features
- Monitors cylinder pressures on reciprocating compressors with high accuracy
- Generates eight proportional values (PPLs) per channel for single and combined chamber analysis
- Provides critical operational and safety data for machinery protection
- Configurable alarm thresholds allow early warning for abnormal conditions
- Compact and robust design suitable for industrial environments
Proportional Values (PPLs)
Single Chamber PPLs:
- Discharge Pressure
- Suction Pressure
- Maximum Pressure
- Minimum Pressure
- Compression Ratio
Combined Channel PPLs:
- Peak Rod Compression
- Peak Rod Tension
- Degree of Rod Reversal
