Function and Working Principle
The 330703-000-040-50-02-05 Proximity Probe operates by using eddy current sensing technology to measure shaft movement and displacement.
The working process includes:
- The probe generates an electromagnetic field at the sensing tip.
- The rotating shaft influences the electromagnetic field based on the distance between the shaft and probe.
- The sensor detects changes in the field caused by shaft movement.
- The measurement signal is transmitted to the monitoring system.
- The system analyzes the signal to determine vibration levels and shaft position.
The non-contact measurement method allows the probe to operate continuously without mechanical contact damage, making it suitable for high-speed rotating equipment.
