Product Description
Product Overview
The Emerson PR6423/010-010+CON021 is an 8mm Eddy Current Sensor designed for non-contact measurement of radial and axial shaft dynamic displacement, position, eccentricity, and speed. It is ideal for critical turbomachinery applications such as steam, gas, and hydro turbines, compressors, gearboxes, pumps, and fans.
The CON021 Eddy Current Signal Converter processes sensor signals with high accuracy, ensuring reliable monitoring of rotating machinery.
