Emerson Epro CON021+PR6423/01H-030 Eddy Current Sensor System

Overview

The Emerson EPRO CON021 + PR6423/01H-030 is a high-precision eddy current sensor system. It measures shaft vibration and displacement without contact. The system suits turbines, compressors, gearboxes, and pumps in harsh industrial environments. The PR6423/01H-030 sensor works with the CON021 converter for real-time monitoring. It uses an 8 mm sensor tip with M10×1 thread for standard mounting. The system tracks radial and axial shaft displacement, position, eccentricity, and rotational speed.
