Function and Working Principle
The probe operates on eddy-current displacement measurement:
- The probe tip generates a high-frequency electromagnetic field.
- A conductive rotating shaft induces eddy currents.
- Changes in the gap between probe and shaft alter the electromagnetic field.
- These changes are converted into electrical signals proportional to shaft vibration and position.
This non-contact method ensures no physical wear and supports long-term stable operation.
