Overview
The Emerson PR6423/006-131 is an 8mm Eddy Current Sensor designed for non-contact measurement in turbomachinery. Paired with the CON041 signal converter, it monitors shaft displacement, position, eccentricity, and speed. This solution supports steam, gas, and hydro turbines, compressors, gearboxes, pumps, and fans.
