Working Principle
The 330704-005-040-10-01-00 operates using proven eddy current sensing technology.
A high-frequency electromagnetic field is generated at the probe tip. When positioned close to a conductive rotating shaft, eddy currents are induced on the shaft surface. Variations in the distance between the probe and the shaft change the strength of the electromagnetic field, producing proportional electrical signals.
These signals are processed by a compatible Proximitor Sensor, providing precise measurements for:
- Radial shaft vibration
- Axial shaft position
- Rotor displacement
- Shaft eccentricity
- Dynamic machine movement
This non-contact measurement principle eliminates mechanical wear and enables highly reliable long-term monitoring.
