Product Overview
The Epro PR6423/003-031-CN 8mm Eddy Current Sensor is a non-contact displacement measurement probe used for monitoring shaft position, vibration, and mechanical movement in rotating machinery. It belongs to the Epro PR6423 series and is mainly applied in machinery protection and condition monitoring systems.
The sensor uses eddy current technology to detect changes in the distance between the probe tip and a conductive rotating target. By continuously measuring shaft movement without physical contact, it provides reliable displacement feedback for equipment health analysis.
The PR6423/003-031-CN is commonly installed on critical rotating equipment such as turbines, compressors, generators, and pumps. It is normally connected with a compatible signal converter and monitoring module to build a complete vibration and shaft displacement monitoring system.

Working Principle
The PR6423/003-031-CN operates using the eddy current measurement principle.
Signal process:
Rotating Shaft → PR6423/003-031-CN Eddy Current Sensor → Signal Converter → Monitoring System → Protection Logic
Operating steps:
- The sensor generates a high-frequency electromagnetic field at the probe tip.
- The conductive shaft surface affects the electromagnetic field according to the distance between the shaft and sensor.
- The sensor detects changes in eddy current intensity caused by shaft movement.
- The displacement information is converted into an electrical output signal.
- The monitoring system analyzes vibration and position changes for equipment condition evaluation.
Because measurement is performed without direct contact, the sensor is suitable for continuous monitoring of high-speed rotating components.
