Bently Nevada 3500/77M 176449-07V
(Reciprocating Cylinder Pressure Monitor Module)
Overview
The Bently Nevada 3500/77M 176449-07V is a high-performance 4-channel cylinder pressure monitoring module designed for use within the 3500 Series Machinery Protection System. It is primarily used to monitor reciprocating compressors, providing real-time pressure analysis and critical machinery protection.
This module accepts input from approved pressure transducers, processes the signals, and compares them with user-defined alarm setpoints to ensure safe and efficient operation.
Key Features
- 4-channel monitoring system for cylinder pressure inputs
- Compatible with Bently Nevada pressure transducers
- Real-time signal conditioning and analysis
- Configurable Alert and Danger alarms
- Provides continuous machinery protection
- Designed for reciprocating compressor applications
- Seamless integration into 3500 rack systems
Measured Parameters
Each channel can generate multiple calculated values, including:
Basic Pressure Values
- Discharge Pressure
- Suction Pressure
- Maximum Pressure
- Minimum Pressure
- Compression Ratio
Advanced Calculations
- Peak Rod Compression
- Peak Rod Tension
- Degree of Rod Reversal
These parameters help operators evaluate compressor performance and detect abnormal conditions early.
