Function and Working Principle
The 21500-12-26-05-02 operates on eddy-current sensing:
- The probe tip generates a high-frequency electromagnetic field.
- When positioned near a conductive target such as a rotating shaft, eddy currents are induced in the target material.
- Variations in the gap between the probe and the target alter the electromagnetic field.
- These changes are converted into electrical signals proportional to shaft displacement and vibration.
This non-contact measurement ensures minimal wear and high reliability for continuous operation.
