Description
Bently 3500 40M
Technical Specifications
- Model Number: 3500/40M
- Channel Count: 4 independent channels
- Input Signal: -10 VDC to +10 VDC (from Proximitor)
- System Compatibility: Bently Nevada 3500 Framework
Key Features
- Versatile Input Scaling: Software-configurable to accept various sensor sensitivities (e.g., 200 mV/mil, 100 mV/mil).
- Advanced Filtering: Built-in digital filters to remove noise and extract precise position data.
- Comprehensive Alarming: Independent Alert and Danger setpoints for both static position and dynamic vibration.
Application Scenarios
Deployed on all large rotating machinery with oil-film bearings to monitor thrust bearing wear, rotor bow, and casing expansion in real-time.
Performance Parameters
- Accuracy: ±1% of full scale
- Input Impedance: > 100 kΩ
Material Composition
High-reliability electronic components housed in a shielded, flame-retardant enclosure to prevent interference from adjacent high-voltage modules.
Structural Characteristics
Full-height module with four front-panel BNC connectors and individual channel status indicators. Designed for hot-swapping without framework disruption.
Working Principle
Conditions the analog input signals, performs high-resolution analog-to-digital conversion, and applies digital signal processing to extract precise position values, which are then evaluated against configured alarm limits.
Installation Requirements
Install in any available slot to the right of the TDI module. Ensure proper cable shielding and single-point grounding to prevent ground loops.
Usage Precautions
Verify the correct sensor sensitivity is entered in the configuration software. Incorrect scaling will result in false position readings and potential nuisance trips.
