Function and Working Principle
The Bently Nevada 330701-00-15-50-01-CN Eddy Current Probe operates based on electromagnetic eddy current measurement principles.
During operation, the probe generates an electromagnetic field near the rotating shaft. When the distance between the probe and the shaft changes, the electromagnetic characteristics change accordingly. The sensor converts these variations into electrical signals representing shaft movement and vibration levels.
The working process includes:
- Generating an electromagnetic field through the probe tip.
- Detecting changes in the shaft-to-probe gap.
- Converting displacement variations into electrical signals.
- Sending measurement data to monitoring equipment.
- Supporting machinery condition analysis and protection.
The probe is mainly used for:
- Shaft vibration measurement
- Radial displacement monitoring
- Rotor position detection
- Equipment protection monitoring
- Predictive maintenance applications
