Working Principle
The Bently Nevada 330703-00-00-60-10-02-00 Proximity Probe operates based on eddy current measurement technology.
The probe generates a high-frequency electromagnetic field from the sensing tip. When the distance between the probe and the rotating shaft changes, the electromagnetic field changes accordingly. These variations are converted into electrical signals that represent shaft displacement and vibration conditions.
The operating process includes:
- The probe generates an electromagnetic sensing field.
- The rotating shaft changes the gap distance from the probe tip.
- The sensor detects changes in the electromagnetic field.
- The system converts the signal into displacement data.
- The monitoring system analyzes machine operating conditions.
Because the sensor operates without direct mechanical contact, it provides stable measurement performance while avoiding wear caused by friction.
