CON021 + PR6423/01H-O30 by Emerson EPRO Advanced Eddy Current Sensor System

Description

TheCON021is part of Emerson’sEPRO eddy current monitoring system, designed fornon-contact measurement of shaft vibration and displacement. It works in combination with sensors such as thePR6422, PR6423, PR6424, PR6425, PR6426, and PR6453, providing highly accurate monitoring of radial and axial shaft movement. Moreover, the CON021 is widely used insteam, gas, and hydro turbines, as well as large compressors and pumps, where precise shaft position monitoring is critical for reliability and safety. Itsfast response time (<15 μs)and wide frequency range (up to 20 kHz) make it suitable for dynamic machinery diagnostics. ThePR6423/01H-O30is a high-precision eddy current proximity sensor designed fornon-contact shaft monitoringin critical rotating machinery. It measuresdynamic displacement, position, eccentricity, and shaft speedwith exceptional linearity and stability. Engineered for use insteam, gas, and hydro turbines, as well ascompressors and pumps, it ensures reliable protection and performance in demanding environments. This probe is typically paired with theCON021 signal converter, forming a complete eddy current measurement chain used in predictive maintenance and machinery protection systems. Together, they provide fast response times, robust diagnostics, and accurate shaft behavior insights-helping reduce unplanned downtime and improve asset reliability.
