Product Overview

The Epro PR6423/002-131+CON031 Eddy Current Sensor System is a non-contact displacement measurement solution consisting of an 8 mm eddy current probe and a matching CON031 signal converter. It is mainly used for vibration monitoring, shaft displacement measurement, and mechanical condition monitoring of rotating equipment.

In industrial machinery such as turbines, compressors, pumps, and generators, accurate measurement of shaft position and vibration is essential for preventing unexpected failures. The PR6423/002-131 probe detects changes in the distance between the sensor tip and the rotating shaft surface, while the CON031 signal converter converts the probe output into a standardized signal suitable for monitoring and protection systems.

This sensor system is commonly integrated with Epro/Emerson vibration monitoring platforms and works together with vibration monitoring racks, protection modules, data acquisition systems, and industrial control systems.

Working Principle

The PR6423/002-131+CON031 operates based on the eddy current measurement principle.

Typical measurement process:

Rotating Shaft → Eddy Current Probe → CON031 Signal Converter → Monitoring System → Protection / Control Logic

Operating process:

1. The probe generates a high-frequency electromagnetic field near the rotating shaft surface.
2. When the shaft position changes, the electromagnetic field interaction changes.
3. The sensor detects variations caused by the distance between probe tip and shaft.
4. The CON031 converter processes the probe signal and converts it into a usable monitoring output.
5. The vibration monitoring system analyzes shaft displacement and provides alarms or protection actions when abnormal conditions occur.

This non-contact measurement method allows continuous monitoring without physical contact with the rotating component.
