Description

Bently 3500/20-01-02-00

Technical Specifications

  • Module Type: 4-Channel Proximitor/Seismic Monitor
  • Configuration: 01-02-00
  • Sensor Compatibility: 3300 XL Proximitor and 330500 Velomitor
  • System Integration: 3500 Full-Height or Mini Frame

Functional Features

  • Multi-Parameter Measurement: Processes raw sensor signals to provide accurate radial vibration, axial displacement, and absolute casing vibration data.
  • Independent Channel Logic: Each of the four channels can be independently configured for specific alarm and danger (trip) setpoints via the 3500 Rack Configuration Software.
  • High-Speed Relay Output: Provides millisecond-level response times for driving external machinery protection relays and PLCs.

Application Scenarios
Extensively deployed in power generation, petrochemical, and metallurgical industries to monitor the bearing housings of steam turbines, compressors, pumps, and large motors.

Performance Parameters

  • Measurement Accuracy: High-resolution digital signal processing
  • Frequency Response: DC to 10 kHz (for proximity inputs)
  • Operating Temperature: -30°C to +65°C

Material Composition
Industrial-grade electronic components, conformal-coated printed circuit boards, and a ruggedized metallic shielding enclosure.

Structural Characteristics
Standard full-height 3500 rack module featuring front-panel status LEDs for each channel and rear high-density backplane connectors.

Working Principle
Receives high-frequency impedance signals from proximity probes or velocity signals from seismic sensors, converts them via high-resolution ADCs, and executes real-time algorithmic processing to extract vibration metrics.

Installation Requirements
Must be installed in an available slot within a 3500 rack. 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.
