Product Overview
The Epro PR6423/002-031-CN 8mm Eddy Current Sensor is a non-contact displacement measurement sensor used in rotating machinery monitoring and protection systems. It belongs to the Epro PR6423 series and is mainly applied for detecting shaft vibration, relative displacement, and mechanical position changes in critical industrial equipment.
The sensor uses eddy current measurement technology to detect the distance between the probe tip and a conductive target surface without physical contact. This operating method allows stable measurement on high-speed rotating equipment while avoiding mechanical wear caused by traditional contact measurement methods.
The PR6423/002-031-CN is typically installed near rotating shafts in turbines, compressors, generators, pumps, and other large industrial machines. It provides continuous displacement information to compatible signal converters and monitoring systems, helping engineers evaluate equipment condition and identify abnormal mechanical movement.
As a sensing component in machinery protection systems, the sensor plays an important role in predictive maintenance strategies by providing accurate vibration and position feedback during normal machine operation.

Working Principle
The Epro PR6423/002-031-CN operates based on eddy current sensing technology.
A simplified signal path is:
Rotating Shaft → PR6423/002-031-CN Eddy Current Sensor → Signal Converter → Monitoring System
During operation, the sensor generates a high-frequency electromagnetic field near the machine shaft. When the distance between the sensor probe and the conductive target changes, the generated eddy current characteristics also change.
The sensor detects these changes and converts them into displacement-related electrical signals. These signals are then processed by compatible signal converters and monitoring equipment.
Typical measurement functions include:
- Shaft radial vibration detection
- Relative shaft position monitoring
- Mechanical displacement measurement
- Rotating equipment condition analysis
- Abnormal movement trend identification
The non-contact sensing method allows continuous monitoring without affecting the mechanical operation of the monitored equipment.
Role in Machinery Condition Monitoring Architecture
The PR6423/002-031-CN acts as a measurement component within rotating machinery monitoring systems.
A typical structure can be represented as:
Machine Shaft → Eddy Current Sensor → Signal Converter → Monitoring Module → Protection System
Within this architecture:
- The sensor detects physical shaft movement.
- The converter processes the electrical measurement signal.
- The monitoring module analyzes vibration and displacement conditions.
- The protection system provides alarms or shutdown functions when abnormal conditions occur.
The sensor provides the basic measurement data required for evaluating machine operating health.
