Emerson Epro PR6424/000-130 CON021 Eddy Current Sensor Module

Product Overview

The Emerson Epro PR6424/000-130 CON021 is a high-precision 16mm eddy current sensor designed for non-contacting measurement of shaft vibration and displacement. Part of the specialized Epro product line, this current module serves as the primary transducer for monitoring critical rotating equipment. It operates on the eddy current principle, where high-frequency electromagnetic fields detect the distance between the sensor tip and the metallic target (such as a turbine shaft) without physical contact.

This system is vital for asset protection, providing the high-speed data necessary for detecting shaft eccentricity, axial position, and radial vibration. By converting mechanical movement into precise electrical signals, it enables the Distributed Control System (DCS) to perform real-time health analysis of high-value industrial machinery.
