Product Overview: Epro PR6423/10R-111 8mm Eddy Current Sensor
The Epro PR6423/10R-111 is a high-performance non-contact eddy current sensor engineered for demanding turbomachinery condition monitoring. Designed to deliver precise measurements of shaft displacement, vibration, position, eccentricity, and speed, this sensor is ideal for use in steam turbines, gas turbines, compressors, gearboxes, fans, and pumps.
This model features a reverse mount design with a 3/8″-24 UNF threaded case and an 8mm tip diameter, providing reliable performance in harsh industrial environments. It offers a linear measurement range of 2 mm and complies with stringent international certifications including ATEX, IECEx, CSA, and CE standards for hazardous area applications.
