Product Overview: EPRO PR6423/10R-131 Eddy Current Sensor (8mm)
The EPRO PR6423/10R-131 is a non-contact Eddy Current Sensor engineered for continuous monitoring of radial and axial shaft displacement in rotating machinery. This sensor is tailored for use in steam turbines, gas turbines, hydro turbines, compressors, gearboxes, pumps, and industrial fans, ensuring precision measurement of shaft position, vibration (dynamic displacement), eccentricity, and rotational speed. The PR6423/10R-131 belongs to EPRO’s PR6423 series and features an 8 mm tip diameter with a reverse mount configuration, brass/nickel-plated connectors, and compatibility with Emerson’s MMS3000 system.
