Description
Bently Nevada 109548-01: Precision Shaft Displacement Sensor
Core Technology
Non-contact eddy current sensor detects shaft movement with ±0.5% accuracy. Uses magnetic fields to measure 0-2.0 mm displacement. Built for harsh industrial environments.
Key Specifications
- Model: 109548-01
- Range: 0 to 2.0 mm
- Sensitivity: 0.5 mV/µm
- Temp Range: -40°C to 200°C
- IP Rating: IP67 (dust/waterproof)
- Response: 2 Hz – 10 kHz
Top Uses
- Bearing wear detection
- Shaft bending monitoring
- Gear system diagnostics
- Seal failure prevention
How It Works
Sensor coil creates magnetic field → induces eddy currents on shaft → distance changes alter current strength → precise displacement calculation.
Critical Notes
- Keep 3x sensor diameter from metal objects
- Calibrate every 12 months
