Function and Working Principle
The 21500-04-32-05-02 operates using advanced 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 surface.
- Changes in the probe-to-target distance alter the electromagnetic field characteristics.
- These variations are converted into electrical signals proportional to shaft movement, vibration, and position.
The non-contact measurement principle eliminates mechanical wear and supports long-term reliable operation.
