Working Principle
The Bently Nevada 330703-000-080-10-02-00 Proximity Probe operates using eddy current displacement measurement technology.
The probe generates a high-frequency electromagnetic field at the sensing tip. When the rotating shaft changes position, the distance between the shaft surface and the probe tip changes. This affects the electromagnetic field, and the sensor converts these changes into electrical signals representing shaft movement and vibration.
The measurement process includes:
- The probe produces an electromagnetic sensing field.
- The rotating shaft changes the probe gap distance.
- The sensor detects variations in the electromagnetic field.
- The system converts the changes into displacement signals.
- The monitoring system evaluates machine operating conditions.
The non-contact design eliminates mechanical friction between the sensor and shaft, providing stable operation and extended service life.
