Function and Working Principle
The PR6423/000-140-CN operates by generating a high-frequency electromagnetic field around the sensor tip. When a conductive rotating shaft enters the sensing area, eddy currents are induced on the shaft surface. Changes in the distance between the shaft and the sensor alter the electromagnetic field characteristics, enabling accurate displacement measurement.
This enables:
Continuous non-contact shaft monitoring
High-precision vibration measurement
Real-time displacement analysis
Reliable machinery condition monitoring
Because the sensor operates without physical contact, it minimizes mechanical wear and ensures stable long-term monitoring performance.
