Product Overview
The Epro PR6423/003-030-CN+CON021 Eddy Current Sensor System is a non-contact displacement monitoring assembly consisting of an 8 mm eddy current sensor probe and a CON021 signal converter. It is mainly used for measuring shaft displacement, vibration, and relative movement in critical rotating machinery.
The sensor detects changes in the distance between the probe tip and the rotating shaft surface through eddy current technology. The CON021 converter processes the probe signal and converts it into a suitable output for connection with machinery monitoring and protection systems.
This sensor combination is commonly used in applications such as steam turbines, gas turbines, compressors, generators, and pumps where accurate shaft vibration and position monitoring are required. It provides a compact measurement solution for integrating mechanical condition data into industrial control and protection systems.

Working Principle
The PR6423/003-030-CN+CON021 operates based on electromagnetic eddy current measurement technology.
Signal process:
Rotating Shaft → PR6423/003-030-CN Sensor → CON021 Converter → Monitoring Module → Protection System
Operating process:
- The sensor probe generates an electromagnetic field near the conductive shaft surface.
- Shaft movement changes the eddy current response between the target and sensor.
- The probe converts this change into an electrical measurement signal.
- The CON021 signal converter processes and conditions the sensor output.
- The monitoring system analyzes displacement and vibration data for equipment status evaluation.
This non-contact method allows the sensor to measure rotating components continuously without physical wear.
