Overview
The Epro PR6423/014-010+CON021 is an 8 mm Eddy Current Sensor System designed for non-contact measurement of shaft vibration, displacement, position, and speed in rotating machinery monitoring applications.
The system combines an 8 mm eddy current probe with the CON021 signal converter to provide accurate and stable measurement signals for machinery protection systems. It is mainly used for detecting dynamic shaft movement and mechanical condition changes without direct contact with rotating components.

Applications
Turbine Monitoring
The Epro PR6423/014-010+CON021 is used for monitoring shaft vibration and displacement in steam turbines, gas turbines, and hydro turbines to improve equipment reliability.
Compressor Condition Monitoring
The sensor provides accurate shaft movement measurement for compressors, helping identify abnormal operating conditions and mechanical changes.
Generator Protection
It supports generator monitoring by detecting shaft position variations and vibration behavior during operation.
Pump and Fan Monitoring
The system is suitable for industrial pumps, fans, and rotating equipment where stable shaft condition measurement is required.
Gearbox Monitoring
It helps monitor rotating components inside gearboxes by providing accurate displacement and vibration signals.
How It Works
The Epro PR6423/014-010+CON021 works based on eddy current sensing technology.
The sensor probe generates an electromagnetic field near the rotating shaft. When the distance between the probe and the conductive shaft surface changes, the electrical characteristics of the sensor output change accordingly.
The CON021 converter processes the probe signal and converts it into a suitable measurement output for machinery monitoring and protection systems.
The typical signal process is:
Rotating Shaft → PR6423 Eddy Current Probe → CON021 Converter → Monitoring System
Because the sensor operates without physical contact with the shaft, it provides stable measurement performance while avoiding mechanical wear during high-speed operation.
