4. Product Working Principle
The probe operates by generating a high-frequency electromagnetic field at the probe tip.
When the probe is placed near a conductive rotating shaft, eddy currents are induced on the surface of the shaft.
The strength of this interaction changes with the distance between the probe and the shaft.
This variation is converted into a proportional electrical signal, which is then processed by a monitoring system to determine vibration and displacement characteristics.
