Description
Bently 3500/42-01-00
Technical Specifications
- Module Type: 4-Channel Displacement Monitor
- Configuration: 01-00
- Sensor Compatibility: Bently Nevada 3300 XL Proximitor systems
- Measurement Types: Radial vibration, axial displacement, eccentricity, and shaft position.
Functional Features
- Comprehensive Position Monitoring: Accurately tracks static and dynamic displacement to detect thrust bearing wear and rotor instability.
- Programmable Setpoints: Allows independent configuration of alarm and danger setpoints for each active static value.
- TMR Redundancy Support: Compatible with Triple Modular Redundant (TMR) I/O configurations for critical safety applications.
Application Scenarios
Critical for monitoring axial displacement and eccentricity on large steam turbines, generators, and centrifugal compressors.
Performance Parameters
- Measurement Accuracy: High-precision digital signal processing
- Response Time: Millisecond-level relay response for trip protection
- Operating Temperature: -30°C to +65°C
Material Composition
Industrial-grade electronic components, conformal-coated PCBs, and a ruggedized metallic shielding enclosure.
Structural Characteristics
Standard full-height 3500 rack module with front-panel status LEDs and rear high-density backplane connectors.
Working Principle
Receives high-frequency impedance signals from Proximitor transducers, converts them to digital data via high-resolution ADCs, and executes real-time algorithmic processing to extract displacement metrics.
Installation Requirements
Must be installed in an available slot within a 3500 full-height or mini frame. Ensure the backplane connector is fully seated and secure the front panel mounting screws.
Usage Precautions
Always use the 3500 Rack Configuration Software to verify channel parameters after installation. Never remove or insert the module while the rack power is energized to prevent backplane damage.
