Product Overview

The PR6426/010-140 is a high-performance inductive displacement sensor from the Emerson EPRO family, specifically engineered for non-contact measurement of shaft motion in heavy-duty rotating machinery. This transducer utilizes eddy current technology to capture precise radial vibration and axial position data, providing the high-resolution feedback necessary for early-stage fault detection. While the model was officially phased out of production at the end of 2018, it remains a vital component for the maintenance and repair of legacy Distributed Control Systems (DCS) and AMS machinery protection racks. By delivering consistent, real-time data, the sensor enables operators to mitigate the risk of mechanical failure in high-value assets.
