The eddy current probe emits a high-frequency excitation field across an initial air gap of 0.5 mm to track dynamic positional variations relative to conductive ferromagnetic shaft surfaces. Physical surface gap displacements alter the electromagnetic impedance, converting mechanical motion into continuous analog signals for diagnostic evaluation without physical mechanical wear.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003ePR6423\/011-100\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eEmerson\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eUnited States\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003eApprox. 0.26 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-35 to +180 deg C (sensor incl. cable)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003eStandard loop power dissipation via signal converter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasurement Range\u003c\/td\u003e\n\u003ctd\u003e2 mm (80 mils)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInitial Air Gap\u003c\/td\u003e\n\u003ctd\u003e0.5 mm (20 mils)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eScale Factor (ISF)\u003c\/td\u003e\n\u003ctd\u003e8 V\/mm (203.2 mV\/mil) +\/-5% (0 to 45 deg C)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLinear Deviation (DSL)\u003c\/td\u003e\n\u003ctd\u003e+\/-0.025 mm (+\/-1 mil) within 0 to 45 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Frequency\u003c\/td\u003e\n\u003ctd\u003e30 kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum Shaft Diameter\u003c\/td\u003e\n\u003ctd\u003e25 mm (0.79 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTarget Material\u003c\/td\u003e\n\u003ctd\u003eFerromagnetic steel (42CrMo4 \/ AISI 4140 standard)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProtection Class\u003c\/td\u003e\n\u003ctd\u003eIP66 (IEC 60529)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConverter Compatibility\u003c\/td\u003e\n\u003ctd\u003eCON021 signal converter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003e4-20 mA HART Loop Protocol \u0026amp; Channel Isolation\u003c\/h3\u003e\n\u003cp\u003eWhen interfaced with CON021 signal converter modules, the transducer drive circuitry processes continuous high-frequency excitation currents while providing 4-20 mA HART loop protocol compatibility for process loops and asset management networks. On-board signal conditioning features galvanic channel-to-channel isolation, suppressing common-mode potential differences and earth current loops in dense monitoring racks. Built-in thermal compensation stabilizes the 8 V\/mm scale factor output across ambient temperature variations, limiting deviation tolerances within +\/-0.025 mm.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the primary function of the CON021 signal converter when paired with this sensor?\u003c\/p\u003e\n\u003cp\u003eA: The CON021 module energizes the PR6423\/011-100 probe coil with high-frequency drive current and demodulates raw impedance shifts into normalized proportional analog outputs for machinery protection systems.\u003c\/p\u003e\n\u003cp\u003eQ: What are the minimum target geometry constraints for maintaining accurate scale sensitivity?\u003c\/p\u003e\n\u003cp\u003eA: The sensor requires a minimum shaft target diameter of 25 mm and must be aimed against calibrated 42CrMo4 or AISI 4140 ferromagnetic steel surfaces to maintain the 8 V\/mm scale factor.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eEnsure an unobstructed metallic clearance radius equal to at least 1.5 times the probe tip diameter to eliminate uncalibrated inductive loading from surrounding machine walls. Set the mechanical standoff distance to achieve the nominal initial air gap of 0.5 mm during machine offline calibration. Route the sensor cable inside grounded metallic conduit isolated from high-voltage motor feeds and VFD wiring. Connect the cable shield braid to the system technical ground at a single cabinet earth point to avoid circulating ground loops.\u003c\/p\u003e","brand":"EMERSON","offers":[{"title":"Default Title","offer_id":53347152003381,"sku":"PR6423\/011-100","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/CON021_PR6423014-010_52e18d4f-85bb-4a48-a735-e736b2a166fb.png?v=1787204682","url":"https:\/\/www.5gplc.com\/products\/emerson-pr6423-011-100-proximity-sensors","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
