Working Principle
The Bently Nevada 330704-000-050-10-02-CN Proximity Probe operates using eddy current sensing technology to measure shaft movement without direct contact.
The operating process includes:
- The probe generates an electromagnetic field near the rotating shaft.
- The shaft surface affects the electromagnetic field according to the measurement gap.
- The probe detects changes caused by shaft vibration and displacement.
- The sensor converts the detected changes into electrical output signals.
- The monitoring system analyzes the data for machinery condition evaluation.
This non-contact measurement method reduces mechanical wear, improves measurement stability, and supports continuous monitoring of high-speed rotating equipment.
