Industrial Non-Contact Displacement Sensor for Turbomachinery Monitoring
The Epro PR6423/10R-030-CN 8 mm Eddy Current Sensor is a precision non-contact measurement device designed for monitoring displacement, vibration, and position in rotating machinery. Built for demanding industrial environments, this sensor uses advanced eddy-current technology to deliver highly accurate and stable readings without mechanical contact, ensuring long service life and reliable operation.
Commonly used in turbomachinery protection systems, the PR6423 series is engineered to measure radial and axial shaft displacement, eccentricity, and vibration in critical equipment such as turbines, compressors, pumps, and gearboxes. Its rugged stainless-steel housing and industrial-grade cable ensure durability in high-temperature and high-vibration environments.

Typical Industrial Applications
The PR6423/10R-030-CN is widely used in critical machinery monitoring systems where precise non-contact measurement is required:
-
Steam, gas, and hydro turbine shaft monitoring
-
Compressor vibration and displacement measurement
-
Pump and fan shaft position detection
-
Gearbox eccentricity and rotational analysis
-
Industrial rotating equipment protection systems
Because the sensor never physically contacts the measured surface, it ensures accurate readings even in high-speed rotating environments.
