Designers created this Emerson EPRO CON021+PR6423/010-000-CN 8mm Eddy Current Sensor for critical turbomachinery applications, such as steam, gas, and hydro turbines, compressors, gearboxes, pumps, and fans. It measures both radial and axial shaft dynamic displacement, position, eccentricity, and speed.
