Description
Bently 3500 40 176449-01
Technical Specifications
- Model: 3500/40 (176449-01)
- Sensor Type: Eddy Current Proximity Probes
- Channels: 4 independent channels
- System Compatibility: 3500 Series Machinery Protection System
Functional Features
- High-Precision Measurement: Provides high-resolution displacement measurement to accurately capture minute clearance changes.
- Flexible Configuration: Supports flexible configuration of various sensor sensitivities and ranges, meeting API 670 standards.
- Programmable Alarms: Each channel can be independently configured with alarm points and delays.
Application Scenarios
Widely used for axial displacement, differential expansion, eccentricity, and valve position monitoring in steam turbines and compressors.
Performance Parameters
- Measurement Accuracy: Extremely high, dynamic range ≥ 100 dB
- Operating Temperature: -30°C to +65°C
Material Composition
High-strength flame-retardant enclosure with internal circuit boards treated with tri-proof coating.
Structural Characteristics
Standard 3500 module size with front-panel channel status and alarm indicator LEDs.
Working Principle
Receives DC voltage signals from proximitors, performs high-precision A/D conversion, and the microprocessor calculates actual mechanical displacement based on configured zero and full-scale values, comparing them against alarm thresholds.
Installation Requirements
Insert into the designated slot in the 3500 rack. Sensor wiring must use shielded cables, and proper grounding of the proximitors must be ensured.
Precautions for Use
Accurately input sensor sensitivity (e.g., 7.87 mV/μm) and initial gap voltage during configuration. Re-verify system linearity after module replacement.
