The Emerson PR6423/002-030 CON021 is an eddy current sensor and signal converter system designed for critical turbomachinery applications such as steam, gas, and hydro turbines, compressors, gearboxes, pumps, and fans to measure radial and axial shaft dynamic displacement, position, eccentricity, and speed. The PR6423/002-030 non-contact sensor operates with a PEEK (Polyether Ether Ketone) tip, stainless steel case, and PTFE cable. The system integrates with the CON021 eddy current signal converter to convert probe displacement signals into standardized voltage outputs.
