Function and Working Principle
The PR6423/000-031-CN operates by generating a high-frequency electromagnetic field around the sensor tip. When a conductive target such as a rotating shaft enters the sensing range, eddy currents are induced on the target surface. Variations in the target distance change the electromagnetic field characteristics, allowing precise displacement detection.
This enables:
Continuous non-contact shaft monitoring
High-precision vibration measurement
Real-time displacement analysis
Reliable machinery condition monitoring
Because there is no physical contact between the sensor and the rotating shaft, mechanical wear is minimized and long-term operational stability is improved.
