To ensure output linearity, the system necessitates precise gap voltage validation during commissioning. The converter is designed to center its output around a nominal -10 VDC target, corresponding to the 1.5 mm center gap. Maintenance of this baseline is required for accurate tracking of shaft radial vibration and axial position. Deviations from the -10 VDC nominal gap voltage indicate potential installation misalignment, transducer saturation, or degradation of the conductive target surface, which must be addressed to prevent signal distortion.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can this sensor be used on shafts with non-ferromagnetic materials?\u003c\/p\u003e\n\u003cp\u003eA: The sensitivity and linearity are calibrated for electrically conducting steel. Usage on materials with different electrical conductivity or magnetic permeability will require a recalibration of the signal converter's sensitivity factor.\u003c\/p\u003e\n\u003cp\u003eQ: How does shaft diameter affect the measurement accuracy?\u003c\/p\u003e\n\u003cp\u003eA: A minimum shaft diameter of 25 mm is required to maintain the specified flux density. If the shaft diameter is smaller, the sensor output will exhibit non-linearities and reduced sensitivity compared to the factory calibration.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eEnsure the mounting bracket is rigid to prevent mechanical resonances from influencing the transducer output.\u003c\/li\u003e\n\u003cli\u003eInstall the probe at the 1.5 mm nominal gap using a non-conductive feeler gauge to avoid damaging the sensor tip.\u003c\/li\u003e\n\u003cli\u003eVerify that the shaft surface at the measurement location is free of scratches, burrs, or non-conductive coatings.\u003c\/li\u003e\n\u003cli\u003eRoute signal cabling through grounded metallic conduit, keeping lines physically separated from high-current power cables to mitigate electromagnetic interference.\u003c\/li\u003e\n\u003cli\u003eGround the system shield exclusively at the monitoring system (DCS\/TSI) rack to prevent ground-loop current injection into the sensor signal.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"EMERSON","offers":[{"title":"Default Title","offer_id":53009101947189,"sku":"CON021+PR6423\/003-040","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/CON010_PR6423010-120_26872261-47f1-4ca5-981e-7ada3653a97a.png?v=1781684137","url":"https:\/\/www.5gplc.com\/products\/emerson-epro-pr6423-003-040-con021-eddy-current-displacement-transducer","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
