Working Principle
The Bently Nevada 330703-000-100-10-02-00 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 moves relative to the sensor, the distance between the shaft surface and the probe changes. These changes influence the electromagnetic field and are converted into electrical signals representing shaft displacement and vibration conditions.
The measurement process includes:
- The probe generates an electromagnetic sensing field.
- The rotating shaft changes the probe gap distance.
- The sensor detects electromagnetic variations.
- The system converts the signal into displacement data.
- The monitoring system evaluates machine operating conditions.
The non-contact sensing method eliminates mechanical wear and provides stable measurement performance for continuous machinery monitoring.
