Description

Bently 3500 45 176449-04

Technical Specifications

  • Model: 3500/45 (176449-04)
  • Channels: 4 independent monitoring channels
  • Sensor Compatibility: Bently Nevada Eddy Current Proximity Probes
  • System Compatibility: 3500 Series Machinery Protection System

Functional Features

  • Multi-Parameter Monitoring: Supports simultaneous monitoring of axial displacement, differential expansion, casing expansion, and valve position.
  • Flexible Channel Configuration: Channels 1/2 and 3/4 can be independently configured for different monitoring functions.
  • Programmable Alarms: Each channel supports independent Alert and Danger alarm setpoints with configurable delays.

Application Scenarios
Widely deployed on steam turbines, gas turbines, and large compressors to monitor critical clearances and prevent catastrophic mechanical interference.

Performance Parameters

  • Measurement Accuracy: High-precision digital conversion
  • Operating Temperature: -30°C to +65°C
  • Data Update Rate: Less than 1 second

Material Composition
Constructed with high-strength, flame-retardant industrial plastics and conformal-coated internal circuit boards for superior environmental protection.

Structural Characteristics
Standard 3500 module form factor with front-panel channel status and alarm indicator LEDs, and a precision backplane connector.

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 an available 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 and initial gap voltage during configuration. Re-verify system linearity after module replacement.
