Product Overview
The Epro PR6423/10R-010 is a high-precision 8 mm Eddy Current Sensor engineered for non-contact measurement of radial and axial shaft displacement, eccentricity, and rotational speed. Designed to meet the demanding requirements of rotating machinery such as steam turbines, gas turbines, hydro turbines, compressors, gearboxes, fans, and pumps, this sensor ensures reliable vibration monitoring and condition-based maintenance in critical environments.
This specific variant features 3/8″-24 UNF threads, reverse mounting orientation (denoted by “R”), and is constructed with industrial-grade materials such as stainless steel housing and a PEEK sensor tip to withstand harsh environments.
