Emerson CON021+PR6423/01C-030 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. ThePR6423/01C-030is part of Emerson’sPR6423 seriesof eddy current proximity sensors, engineered fornon-contact shaft monitoringin critical rotating machinery. Paired with theCON021 signal converter, it provides high-accuracy measurements ofshaft vibration, displacement, and eccentricity. Its rugged stainless-steel construction, wide operating temperature range, andATEX certificationmake it ideal for harsh industrial environments such as oil & gas, chemical processing, and power generation. This sensor is widely used in predictive maintenance programs where early detection of misalignment, imbalance, or bearing wear prevents major failures.
