Working Principle
The Bently Nevada 330703-000-060-10-11-00 Proximity Probe operates using eddy current sensing technology.
During operation, the probe generates a high-frequency electromagnetic field at the sensing tip. When the rotating shaft changes position, the gap between the shaft and probe tip varies, causing changes in the electromagnetic field. These changes are converted into electrical signals that represent shaft displacement and vibration levels.
The measurement process includes:
- The probe creates an electromagnetic sensing field.
- The rotating shaft changes the probe gap distance.
- The sensor detects variations in the electromagnetic field.
- The system converts these variations into displacement signals.
- The monitoring system evaluates equipment condition.
The non-contact design eliminates mechanical wear between the sensor and shaft, providing reliable performance for continuous machinery monitoring.
