Epro PR6423/000-040 8mm Eddy-Current Sensor

Product Introduction

The Epro PR6423/000-040 Eddy-Current Sensor is a high-performance proximity probe designed for precise, non-contact measurement of shaft displacement and vibration in rotating machinery. Utilizing the eddy-current principle, the sensor detects changes in the distance between the probe tip and the conductive surface of a rotating shaft, enabling accurate monitoring of machinery conditions such as unbalance, misalignment, and bearing wear.
