Installation validation requires setting the static initial gap voltage offset to approximately 0.5 mm (20 mils), corresponding to the calibrated midpoint of the signal range. The probe tip driver minimizes cross-talk suppression issues when sensors are mounted in orthogonal 90-deg configurations, maintaining signal accuracy for high-speed rotor dynamics and axial thrust position tracking.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the calibrated sensitivity factor for the PR6423\/000-031-CN probe system?\u003c\/p\u003e\n\u003cp\u003eA: The sensor provides an Incremental Scale Factor (ISF) of 8 V\/mm (approximately 203.2 mV\/mil) over its 0 to 2 mm linear measuring span when used with a calibrated signal converter.\u003c\/p\u003e\n\u003cp\u003eQ: What temperature limits apply to the sensor probe tip and integrated cable?\u003c\/p\u003e\n\u003cp\u003eA: The probe head and attached cable withstand continuous operating temperatures ranging from -35 deg C to +180 deg C (with peak short-term capability up to +200 deg C).\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eMaintain a minimum physical distance between adjacent sensor tips to prevent mutual inductive coupling and signal cross-talk.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eThread the M10 x 1 housing into the mounting bracket while measuring the DC gap voltage to set the nominal 0.5 mm physical offset.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eProtect the sensor cable run using flexible metal conduit or internal armor, avoiding sharp bends that exceed the minimum bend radius.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eEnsure the sensor housing maintains solid mechanical earth grounding while keeping the signal cable shield isolated from intermediate conduit enclosures.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EPRO","offers":[{"title":"Default Title","offer_id":45889816363082,"sku":"R6423\/000-031-CN","price":2600.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/8569\/3770\/files\/CON021_PR6423002-001-CN_2_6e3854ee-a225-4637-8f5f-f8c4ad52d804.png?v=1754550612","url":"https:\/\/www.topbrandsplc.com\/products\/emerson-epro-r6423-000-031-cn-8mm-eddy-current-sensor","provider":"Topbrands PLC Limited","version":"1.0","type":"link"}
