Overview
The Epro PR6423/002-100-CN+CON021 is an 8 mm Eddy Current Sensor System designed for non-contact measurement of shaft vibration, displacement, and position in rotating machinery. It is widely used in condition monitoring and protection systems for critical industrial equipment.
The system consists of an eddy current probe and signal converter, providing accurate measurement signals for machinery monitoring applications. By detecting changes in the distance between the sensor probe and the rotating shaft surface, it helps identify abnormal mechanical conditions and supports predictive maintenance.

Applications
Turbine Monitoring
The sensor system is used for monitoring turbine shaft vibration and displacement to maintain stable operation of critical rotating equipment.
Compressor Protection
It provides accurate shaft movement measurement for compressors, helping detect mechanical changes before serious failures occur.
Generator Systems
The sensor supports generator condition monitoring by continuously measuring shaft position and vibration behavior.
Pump Monitoring
It helps monitor rotating pump components and provides important data for equipment maintenance decisions.
Industrial Machinery Protection
The system is suitable for applications requiring continuous monitoring of high-speed rotating machinery.
How It Works
The Epro PR6423/002-100-CN+CON021 operates using eddy current measurement technology.
The sensor probe generates an electromagnetic field near the rotating shaft. When the distance between the probe and the conductive shaft changes, the eddy current effect changes the sensor signal. The CON021 converter processes this signal and provides measurement data to the monitoring system.
The typical signal process is:
Rotating Shaft → PR6423 Sensor Probe → CON021 Converter → Monitoring System
Because the sensor does not require physical contact with the shaft, it provides stable measurement performance while avoiding mechanical wear.
