Product Overview
The Epro PR6423/00R-111 8mm Eddy Current Sensor is a precision non-contact displacement probe used for monitoring shaft movement, vibration, and position changes in rotating machinery.
The sensor belongs to the Epro PR6423 series and uses eddy current measurement technology to detect the distance between the probe tip and a conductive rotating target. Unlike contact-based measurement methods, the sensor can continuously monitor high-speed rotating components without mechanical wear.
In industrial condition monitoring applications, accurate shaft displacement data is essential for evaluating the operating condition of turbines, compressors, generators, pumps, and other critical rotating equipment. The PR6423/00R-111 provides the measurement signal required by compatible converters and machinery protection systems for vibration analysis and equipment diagnostics.

Working Principle
The PR6423/00R-111 operates using electromagnetic eddy current technology to measure changes in shaft position.
The measurement process is:
Rotating Shaft → PR6423/00R-111 Sensor → Signal Converter → Monitoring System
The sensor produces a high-frequency electromagnetic field at the probe tip. When the distance between the sensor and the conductive shaft surface changes, the eddy current effect changes accordingly.
The resulting signal variation represents the displacement between the probe and the rotating component. After signal conversion and processing, the measurement data can be used for:
- Shaft vibration monitoring
- Rotor position detection
- Radial displacement measurement
- Equipment condition analysis
- Machinery protection functions
This non-contact operating method allows stable measurement on rotating equipment operating at high speeds.
Role in a Machinery Protection System
The Epro PR6423/00R-111 functions as a sensing element within rotating machinery protection and diagnostic systems.
A typical measurement structure is:
Machine Shaft → Eddy Current Sensor → Signal Converter → Monitoring Module → Protection System
The sensor continuously monitors shaft movement and provides displacement information to the monitoring system.
For critical assets, this data supports early identification of abnormal mechanical conditions, helping operators reduce unplanned downtime and improve maintenance planning.
