Product Overview
The Epro PR6423/004-010-CN+CON021 Eddy Current Sensor System combines an 8mm PR6423 Eddy Current Sensor with a CON021 Eddy Current Signal Converter to provide a complete non-contact displacement measurement solution for rotating machinery monitoring applications.
The system is mainly used for measuring relative shaft displacement, vibration, and mechanical movement in equipment where continuous condition monitoring is required. By using eddy current measurement technology, the sensor can detect changes in the distance between the probe tip and the conductive target surface without physical contact.
The PR6423 sensor collects the displacement information from the rotating component, while the CON021 signal converter processes the sensor signal and provides a standardized output for connection with monitoring and protection systems.
This type of measurement solution is widely applied in machinery protection systems where early detection of abnormal shaft movement can help reduce unexpected equipment downtime and support predictive maintenance strategies.

Working Principle
The PR6423/004-010-CN+CON021 operates by detecting changes in electromagnetic characteristics between the sensor probe and the monitored metallic target.
A simplified signal path is:
Rotating Shaft → PR6423 Eddy Current Sensor → CON021 Signal Converter → Monitoring System → Protection / Analysis Function
The sensor generates a high-frequency electromagnetic field near the shaft surface. When the distance between the probe and the conductive target changes, the eddy current effect changes accordingly.
The sensor converts these variations into an electrical measurement signal. The CON021 signal converter processes the raw sensor output and converts it into a suitable signal format for the connected monitoring equipment.
The processed displacement information can then be used for vibration analysis, shaft position monitoring, alarm generation, and machinery protection functions.
Because the measurement process does not require direct contact with the rotating component, the system can operate continuously in demanding industrial environments.
Role in Machinery Condition Monitoring Architecture
The PR6423/004-010-CN+CON021 functions as a complete measurement section within a rotating equipment monitoring architecture.
A typical structure is:
Rotating Equipment → Eddy Current Sensor → Signal Converter → Monitoring Module → Protection System
| System Layer | Typical Function |
|---|---|
| Rotating Equipment | Produces mechanical movement |
| Sensor Layer | Detects shaft displacement |
| Signal Conversion Layer | Processes measurement signals |
| Monitoring Layer | Analyzes vibration and position data |
| Protection Layer | Generates alarms and shutdown signals |
| Control Layer | Coordinates equipment operation |
The combination of sensor and converter allows the monitoring system to receive stable displacement data from critical rotating components.
This is particularly important for machinery where shaft vibration, rotor movement, or bearing-related displacement must be monitored continuously.
Industrial Applications
The Epro PR6423/004-010-CN+CON021 is suitable for industrial applications requiring accurate shaft displacement monitoring.
| Application | Typical Use |
|---|---|
| Steam Turbines | Rotor vibration and displacement monitoring |
| Gas Turbines | Shaft movement detection |
| Compressors | Condition monitoring |
| Generators | Shaft position measurement |
| Pumps | Rotating component analysis |
| Power Plant Equipment | Machinery protection systems |
| Process Machinery | Predictive maintenance |
| Industrial Drives | Vibration monitoring |
The final application depends on the machinery design, monitoring platform, and required protection functions.
Installation and Maintenance
Correct installation of both the sensor and signal converter is important for maintaining measurement accuracy.
Recommended maintenance checks include:
- Confirm the complete PR6423/004-010-CN+CON021 model.
- Verify sensor and converter compatibility.
- Check probe mounting position.
- Confirm correct sensor gap adjustment.
