Function and Working Principle
The 21500-00-12-10-02 utilizes eddy-current technology to monitor shaft movement:
- The probe generates a high-frequency electromagnetic field.
- When placed near a conductive target, eddy currents are induced in the target material.
- Variations in the distance between the probe and target alter the eddy current field.
- These changes are converted into electrical signals proportional to shaft displacement and vibration.
The non-contact operating principle eliminates mechanical wear and enables continuous online monitoring.
