Product Overview

The Emerson PR6423/008-130 (designated CON021) is a non-contacting eddy current sensor engineered for high-precision vibration and displacement monitoring. As part of the EPRO product family, this sensor is specifically designed to measure the relative radial or axial shaft motion of rotating machinery. By generating an electromagnetic field that reacts to the proximity of a conductive metallic target, the PR6423/008-130 provides critical real-time data on shaft position and oil-film thickness, serving as a fundamental component in machinery protection and condition monitoring systems.

Industrial Applications

The PR6423/008-130 CON021 is a vital asset for predictive maintenance in heavy industrial sectors. It is extensively deployed in Power Generation for monitoring steam and gas turbine shaft vibration, ensuring that eccentricities do not lead to catastrophic blade contact. In the Oil and Gas industry, it is used on centrifugal compressors and high-speed pumps to detect bearing wear and shaft misalignment. Furthermore, in Hydroelectric facilities, these sensors track the structural health of large vertical turbine shafts. By providing early warning of mechanical instability, the PR6423 series helps operators prevent unplanned outages and extend the lifecycle of expensive rotating assets.
