The 330910-03-20-05-11-00 proximity probe operates based on the principle of eddy current displacement measurement.
A precision coil inside the probe generates a high-frequency electromagnetic field. When the probe approaches the conductive surface of a rotating shaft, the electromagnetic field changes because of eddy current effects.
The probe detects these changes and converts them into an electrical signal representing the distance between the probe tip and the shaft.
The monitoring system processes this signal and provides information about:
The non-contact design allows the probe to operate continuously without mechanical wear, making it ideal for high-speed rotating machinery.
