Product Introduction
The Epro PR6423/00R-010-CN is a high-precision 8mm eddy current sensor designed for non-contact measurement of dynamic displacement, position, eccentricity, and speed in critical turbomachinery applications. It is widely used in steam turbines, gas turbines, compressors, gearboxes, and other rotating machinery where reliability and accuracy are paramount.
This sensor features a reverse mount configuration (R) with an M10x1 threaded case, standard non-armored cable, and a Lemo connector. Its robust construction ensures durability in harsh industrial environments, including high temperatures and hazardous areas.
