Product Overview

The Emerson PR6426/000-040 CON021 is a high-sensitivity inductive displacement sensor specifically engineered for non-contacting measurement of shaft vibration and position in high-speed rotating machinery. As a key component of the Epro product family, this eddy current probe detects microscopic changes in the air gap between the sensor tip and the target material, providing critical feedback to machine protection systems. While often categorized generally in "Eddy Models," this specific unit is essential for monitoring turbine shaft eccentricity, radial vibration, and axial displacement, ensuring the structural integrity of industrial assets through precise electromechanical monitoring.
