Description
Bently 3500 40M140734-01
Technical Specifications
- Part Number: 140734-01
- Module Type: 3500/40M Position Monitor
- Channels: 4 independent channels
- Input Type: Eddy Current Proximity Probes
Key Features
- High-Precision Measurement: Provides 24-bit resolution for highly accurate displacement and position monitoring.
- Dual Measurement: Simultaneously measures static shaft position (e.g., axial displacement) and dynamic vibration.
- Auto-Calibration: Features built-in calibration routines to ensure long-term measurement accuracy.
Application Scenarios
Critical for monitoring axial displacement, differential expansion, and eccentricity in steam turbines, gas turbines, and large compressors to prevent catastrophic rotor-stator rubs.
Performance Parameters
- Resolution: 24-bit ADC
- Frequency Response: DC to 10 kHz (-3 dB)
Material Composition
Ruggedized industrial enclosure with advanced analog front-end circuitry designed for ultra-low noise signal processing.
Structural Characteristics
Full-height module with front-panel BNC inputs for each channel and status LEDs indicating OK, Alert, and Danger conditions.
Working Principle
Receives buffered DC/AC signals from Proximitor signal conditioners. The module digitizes the signals, separates the static (DC) and dynamic (AC) components, and compares them against user-defined alarm setpoints.
Installation Requirements
Connect to Proximitor outputs using shielded coaxial cables. Configure the module’s sensitivity and engineering units via the 3500 Configuration Software to match the sensor system.
Usage Precautions
Ensure the Proximitor sensitivity matches the module configuration. Perform a dynamic calibration check using a calibrated shaker or static gap verification using a micrometer after installation.
