Overview
The Epro PR6424/000-130+CON021/914-100 is a 16 mm Eddy Current Sensor System designed for non-contact measurement of shaft vibration, displacement, position, and eccentricity in large rotating machinery.
The system combines the PR6424 eddy current probe with the CON021 signal converter and is designed for applications requiring accurate and stable monitoring of rotating equipment. It detects changes in the distance between the sensor tip and the rotating shaft surface, providing important condition data for machinery protection and predictive maintenance.

Applications
Steam Turbine Monitoring
The sensor system is used to monitor shaft vibration, axial movement, and displacement changes in steam turbine systems to support reliable operation.
Gas Turbine Protection
It provides continuous shaft condition measurement for gas turbines and helps detect abnormal mechanical movement during operation.
Compressor Monitoring
The PR6424 sensor system helps monitor compressor shaft behavior and provides data for early fault detection.
Generator Condition Monitoring
It supports generator protection applications by measuring shaft displacement and vibration characteristics.
Large Industrial Machinery
The 16 mm sensor design is suitable for heavy-duty rotating equipment where stable and accurate measurement is required.
How It Works
The Epro PR6424/000-130+CON021/914-100 uses eddy current measurement technology for non-contact shaft monitoring.
The sensor probe generates a high-frequency electromagnetic field near the conductive shaft surface. When the distance between the probe and shaft changes, the electrical characteristics of the sensor signal change accordingly.
The CON021 converter processes the probe signal and converts it into a usable measurement output for machinery monitoring and protection systems.
The typical working process is:
Rotating Shaft → PR6424 Eddy Current Probe → CON021 Converter → Monitoring System
Because the sensor does not physically contact the rotating shaft, it avoids mechanical wear and provides reliable performance in high-speed machinery applications.
