Emerson EPRO PR6423/003-030 8mm Eddy Current Sensor

Overview

The Emerson EPRO PR6423/003-030 is a non-contact sensor designed for critical turbomachinery applications such as steam, gas, and hydro turbines, compressors, gearboxes, pumps, and fans. It is used to measure radial and axial shaft dynamic displacement, position, eccentricity, and speed.
