Function and Working Principle
The Bently Nevada 330703-000-040-50-12-00 Proximity Probe operates using eddy current sensing technology to measure the movement and position of rotating shafts.
The working process includes:
- The probe tip generates a high-frequency electromagnetic field.
- The rotating shaft affects the electromagnetic field according to the changing gap distance.
- The sensor detects variations caused by shaft movement.
- The signal is converted into electrical measurement data.
- The monitoring system analyzes the data to determine vibration levels and shaft position.
The non-contact measurement principle eliminates mechanical contact between the sensor and rotating parts, improving reliability and reducing maintenance requirements.
