EZ1900-040 Emerson Eddy Current Sensor Extension Cable

EZ1900-040 Eddy Current Sensor

Description:

The Eddy Current Sensor is a non-contact sensor designed for critical turbomachinery applications such as steam, gas, and hydro turbines, compressors, gearboxes, pumps, and fans. It is utilized to measure radial and axial shaft dynamic displacement, position, eccentricity, and speed.
