Working Principle
The Bently Nevada 330703-020-110-10-01-05 Proximity Probe operates using eddy current sensing technology to provide accurate non-contact measurement.
The working process includes:
- The probe generates an electromagnetic field near the rotating shaft.
- The shaft surface affects the electromagnetic field based on its distance from the probe tip.
- The probe detects changes caused by shaft vibration and displacement.
- The sensor converts these changes into electrical output signals.
- The monitoring system processes the signal data for equipment condition analysis.
This non-contact sensing method allows continuous operation, reduces mechanical wear, and provides stable monitoring performance for high-speed rotating equipment.
