Description
Bently 3500 70M
Technical Specifications
- Model: 3500/70M
- Channels: 4 independent channels
- Input Type: Eddy Current Proximity Probes
- System Compatibility: 3500 Series Machinery Protection System
Functional Features
- Reciprocating Machinery Protection: Executes specialized measurements including Rod Position, Rod Drop, and Hyper-Compressor monitoring.
- Continuous Monitoring: Compares dynamic and static rod positions against user-programmable alarm setpoints.
- TMR Support: Can be configured in Triple Modular Redundant setups for critical safety applications.
Application Scenarios
Exclusively deployed in oil and gas, petrochemical, and natural gas transmission facilities to protect reciprocating compressors from crosshead, piston, and rod packing failures.
Performance Parameters
- Measurement Accuracy: High precision with advanced diagnostic capabilities
- Operating Temperature: Standard industrial operating range
Material Composition
Constructed with high-strength, flame-retardant industrial plastics and conformal-coated internal circuit boards.
Structural Characteristics
Standard 3500 module form factor with front-panel status LEDs and a precision backplane connector.
Working Principle
Receives high-frequency signals from eddy current probes, calculates the average rod position and drop over the compressor stroke, and triggers alarms when mechanical limits are exceeded.
Installation Requirements
Insert into an available slot in the 3500 rack. Ensure probe cables are properly shielded and routed away from high-voltage interference sources.
Precautions for Use
Accurately configure the compressor stroke length and probe sensitivity in the 3500 Rack Configuration Software. Verify probe mounting hardware is secure and free of mechanical play.
