Function and Working Principle
The 21500-00-28-05-02 operates using eddy-current technology:
- The probe tip generates a high-frequency electromagnetic field.
- When placed near a conductive target, such as a rotating shaft, eddy currents are induced in the target.
- Variations in the gap between the probe and the target modify the electromagnetic field.
- These changes are converted into electrical signals representing shaft displacement and vibration.
The non-contact measurement ensures long-term reliability and eliminates mechanical wear.
