Working Principle High-frequency current in the probe tip coil generates a high-frequency magnetic field. Induced eddy currents in the rotating metal shaft change coil impedance. The proximitor converts impedance change to a voltage proportional to probe-to-shaft distance. Distance variation reflects shaft vibration displacement.
Installation Requirements
- Screw thread into rack measurement hole
- Probe face parallel to shaft surface
- Adjust gap within ±1 mm linear range
- Lock mounting nut
- Coaxial cable to proximitor
- Route cable away from power cables
- Temperature -35 °C to +120 °C
- Calibrate gap voltage with proximitor after power-up
Precautions
- Do not impact probe
- Do not over-bend coaxial cable
- Shaft surface clean and free of rust
- Measuring surface must be ferrous
- Store spares in dry environment
- Periodically calibrate gap
