Product Overview
The Epro PR6423/003-040+CON021 Eddy Current Sensor System is a non-contact displacement monitoring solution that combines an 8 mm eddy current probe with a CON021 signal converter. It is designed for measuring shaft displacement, vibration, and relative movement of rotating equipment in industrial applications.
The sensor detects changes in the gap between the probe tip and the rotating shaft through electromagnetic eddy current technology. The CON021 converter processes the detected signal and converts it into an output suitable for machinery monitoring and protection systems.
This sensor assembly is widely used in rotating machinery such as steam turbines, gas turbines, compressors, generators, and pumps. By continuously monitoring shaft movement, it helps operators identify abnormal operating conditions and improve equipment reliability.

Working Principle
The PR6423/003-040+CON021 operates according to the eddy current displacement measurement principle.
Measurement process:
Rotating Shaft → PR6423/003-040 Probe → CON021 Signal Converter → Monitoring Module → Protection System
Operating steps:
- The eddy current probe generates a high-frequency electromagnetic field near the shaft surface.
- Changes in the shaft-to-probe distance influence the electromagnetic field.
- The sensor detects variations in eddy current intensity caused by shaft movement.
- The CON021 converter processes the sensor output signal.
- The monitoring system receives the converted signal for vibration analysis, alarm monitoring, or equipment protection.
The non-contact measurement method allows reliable monitoring of rotating parts without mechanical friction or wear.
