Product Overview
The Epro PR6423/002-131 8mm Eddy Current Sensor is a non-contact displacement measurement sensor designed for industrial rotating machinery monitoring applications. It belongs to the Epro PR6423 series and is mainly used for detecting shaft vibration, relative displacement, and position changes in rotating equipment.
The sensor applies eddy current measurement technology to monitor the distance between the probe tip and the conductive target surface. Through electromagnetic field variation, the sensor can accurately detect mechanical movement without requiring physical contact with the rotating shaft.
The PR6423/002-131 is commonly installed on critical machinery such as turbines, compressors, generators, pumps, and other rotating equipment where continuous shaft condition monitoring is required. The collected displacement data can be transmitted through compatible signal converters and monitoring systems for vibration analysis and equipment protection.
With an 8mm sensor head design, this model provides a practical solution for applications requiring reliable measurement performance and flexible installation in industrial machinery monitoring systems.

Working Principle
The Epro PR6423/002-131 operates using eddy current displacement sensing technology.
A simplified measurement process is:
Rotating Shaft → PR6423/002-131 Eddy Current Sensor → Signal Converter → Monitoring System
During operation, the sensor generates an electromagnetic field near the rotating shaft surface. When the distance between the sensor tip and the conductive target changes, the eddy current response changes accordingly.
The sensor converts these changes into electrical signals representing displacement variations. After signal processing, the monitoring system can analyze shaft movement, vibration trends, and machine operating conditions.
Typical measurement functions include:
- Shaft radial vibration monitoring
- Relative position measurement
- Displacement change detection
- Mechanical movement analysis
- Rotating equipment condition evaluation
The non-contact measurement method allows long-term monitoring without mechanical interaction with the rotating component.
Role in Machinery Condition Monitoring Architecture
The PR6423/002-131 functions as a sensing element within a complete rotating machinery protection system.
A typical monitoring structure can be represented as:
Machine Shaft → Eddy Current Sensor → Signal Converter → Monitoring Module → Protection System
Within this architecture:
- The sensor detects shaft displacement changes.
- The signal converter processes measurement signals.
- The monitoring module evaluates vibration and position data.
- The protection system generates alarms or control actions.
The sensor provides essential mechanical feedback for maintaining safe and reliable operation of industrial rotating equipment.
