Product Description
Product Overview
The Emerson PR6423/000-031+CON041 is an 8mm Eddy Current Sensor designed for non-contact measurement of radial and axial shaft dynamic displacement, position, eccentricity, and speed. It is suitable for critical turbomachinery applications such as steam, gas, and hydro turbines, compressors, gearboxes, pumps, and fans.
The CON041 Eddy Current Signal Converter is used alongside the PR6423 sensor to process displacement signals with high accuracy, ensuring reliable monitoring of rotating machinery.
