The Epro PR6423/10R-040+CON021 is an 8 mm Eddy Current Sensor System designed for non-contact measurement of shaft vibration, displacement, and position in rotating machinery monitoring applications.
This sensor system combines an eddy current probe with a CON021 signal converter to provide stable and accurate measurement signals for machinery protection and condition monitoring systems. It is designed to detect small changes in the position between the sensor probe and the rotating shaft, helping operators monitor equipment health and identify potential mechanical issues.

| Product Type | 8 mm Eddy Current Sensor |
| Sensor Technology | Eddy Current Measurement |
| Sensor Head Diameter | 8 mm |
| Weight | 0.22 kg |
| Measurement Type | Non-contact Displacement Measurement |
| Main Function | Shaft Vibration and Position Monitoring |
| Application | Rotating Machinery Condition Monitoring |
| System Components | Sensor Probe + CON021 Signal Converter |
The sensor is used for monitoring shaft vibration and displacement in steam turbines, gas turbines, and other high-speed rotating equipment.
It provides accurate shaft movement detection for compressors, helping identify abnormal operating conditions and mechanical changes.
The sensor supports generator monitoring systems by measuring shaft position and vibration characteristics during operation.
It is suitable for industrial pumps and motors where reliable shaft condition monitoring is required.
The sensor system helps improve equipment reliability by providing continuous monitoring data for predictive maintenance programs.
The Epro PR6423/10R-040+CON021 uses eddy current sensing technology to measure shaft movement without physical contact.
The sensor probe generates an electromagnetic field near the conductive rotating shaft. When the distance between the probe and the shaft changes, the electromagnetic characteristics change, allowing the system to calculate displacement and vibration values.
The CON021 converter processes the signal from the sensor probe and converts it into a usable output for machinery monitoring systems.
The typical working process is:
Rotating Shaft → Eddy Current Probe → CON021 Converter → Monitoring System
Because there is no mechanical contact between the sensor and shaft, the system provides stable operation and reduces wear compared with contact measurement methods.
