Function and Working Principle
The Bently Nevada 330703-000-050-10-12-CN Proximity Probe uses eddy current sensing technology to measure shaft position and vibration changes in rotating machinery.
The working process includes:
- The probe generates an electromagnetic field near the rotating shaft.
- The shaft movement changes the distance between the shaft surface and the probe tip.
- The electromagnetic field changes are converted into electrical signals.
- The monitoring system processes the signals to evaluate vibration and displacement conditions.
- Operators use the collected data for equipment protection and maintenance decisions.
The non-contact measurement method eliminates physical contact between the sensor and rotating parts, reducing wear and providing stable long-term measurement performance.
