Overview
The Epro PR6423/004-010+CON021 is an 8 mm Eddy Current Sensor System designed for non-contact measurement of shaft vibration, displacement, position, and rotational conditions in critical rotating machinery.
The system combines an eddy current probe with a signal converter to provide stable measurement signals for machinery protection and condition monitoring applications. It is widely used in equipment where accurate shaft movement detection is required, helping operators identify mechanical changes and improve maintenance planning.

Applications
Turbomachinery Monitoring
The sensor system is used for monitoring shaft vibration and displacement in steam turbines, gas turbines, and other high-value rotating equipment.
Compressor Condition Monitoring
It provides continuous shaft movement measurement for compressors, helping detect abnormal mechanical conditions during operation.
Generator Protection
The system supports generator monitoring by measuring shaft position changes and vibration behavior.
Pump and Motor Monitoring
It helps maintain reliable operation of industrial pumps and motors by providing accurate rotating shaft condition data.
Industrial Machinery Protection
The sensor is suitable for applications where early detection of mechanical faults is important for preventing unexpected downtime.
How It Works
The Epro PR6423/004-010+CON021 operates based on eddy current measurement technology.
The sensor probe creates a high-frequency electromagnetic field near the rotating shaft. When the distance between the probe and the conductive shaft surface changes, the sensor detects the variation and generates a corresponding measurement signal.
The CON021 converter processes the probe signal and converts it into a usable output for machinery monitoring systems.
The typical signal path is:
Rotating Shaft → PR6423 Eddy Current Probe → CON021 Converter → Monitoring System
Because the sensor measures without physical contact, it avoids mechanical wear and provides stable performance in high-speed rotating equipment.
