EPRO Eddy Current Sensors, particularly the PR6422, PR6423, and PR6424 series, are industry-standard probes for non-contact measurement of shaft vibration and position. The sensor architecture utilizes the eddy current principle, featuring a precision-wound coil housed in a robust, ceramic-tipped stainless steel body. Technical characteristics include a wide linear measurement range, high sensitivity to metallic targets, and exceptional resistance to high-pressure and corrosive environments. Functionally, these probes capture real-time data on radial shaft vibration, eccentricity, and axial displacement. When paired with MMS 6000 converters, they provide the accurate sensory feedback necessary for the automatic trip protection of steam turbines and large industrial pumps.
