Working Principle
The Bently Nevada 330703-000-060-10-11-05 Proximity Probe operates using eddy current 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 and probe tip changes, affecting the electromagnetic field. These variations are converted into electrical signals that represent 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 changes into displacement signals.
- The monitoring system evaluates machine operating status.
Because the sensor works without physical contact with rotating components, it minimizes mechanical wear and provides reliable continuous monitoring.
