The sensing system generates a high-frequency electromagnetic field at the probe tip to detect microscopic gaps between the sensor face and target conductive metal surfaces. The associated converter conditions this physical proximity response into a proportional continuous analog output signal for direct processing by machinery monitoring systems.\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\u003ePR6424\/003-030 CON021\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\u003e0.32 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e12.1 cm * 5.2 cm * 16.6 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-30 to +80 deg C (Converter) \/ -35 to +180 deg C (Probe head)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e\u0026lt; 1.2 W (at nominal supply voltage)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasuring Principle\u003c\/td\u003e\n\u003ctd\u003eEddy Current Inductive Proximity\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Signal Range\u003c\/td\u003e\n\u003ctd\u003e4-20 mA HART loop protocol \/ Raw Gap Voltage\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTarget Calibration\u003c\/td\u003e\n\u003ctd\u003eFerromagnetic Steel (42CrMo4 \/ AISI 4140)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannel Isolation\u003c\/td\u003e\n\u003ctd\u003eGalvanic signal isolation to supply power\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; Signal Conditioning\u003c\/h3\u003e\n\u003cp\u003eThe integrated converter circuit employs a 4-20 mA HART loop protocol to transmit primary dynamic displacement variables alongside internal diagnostic field data over standard two-wire connections. Galvanic channel-to-channel isolation prevents ground loop currents from distorting high-frequency displacement signals during multi-channel bearing rack operations. Analog output scaling maintains predictable linearity across the target measuring range, minimizing total loop noise and thermal drift over prolonged continuous operation.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What power supply arrangement is required to power the signal converter?\u003c\/p\u003e\n\u003cp\u003eA: The converter requires an external 24 VDC power supply connected via shielded twisted-pair cabling. Loop power must remain within specified operating voltage thresholds to ensure stable oscillator output.\u003c\/p\u003e\n\u003cp\u003eQ: How does loop shield termination affect signal integrity?\u003c\/p\u003e\n\u003cp\u003eA: Signal cable shielding must be connected to functional earth at a single point, typically at the monitoring cabinet terminal frame, to avoid dual-ground potential differences and loop noise.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eMount the probe tip securely using designated bracketry, ensuring a minimum side-wall clearance of 1.5 times the tip diameter to eliminate extraneous metal interference. Route sensor cables through dedicated grounded metal conduits separated from high-voltage motor supply wiring. Tighten all cable connectors finger-tight plus one-quarter turn to maintain environmental sealing, and apply self-amalgamating tape over external outdoor joints. Maintain a minimum bend radius of 30 mm along extension cables during field installation.\u003c\/p\u003e","brand":"EMERSON","offers":[{"title":"Default Title","offer_id":53346448113973,"sku":"CON021+PR6424\/003-030","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/CON021_PR6424000-130_e78323b7-8369-4885-8c50-3d5404533072.png?v=1787195115","url":"https:\/\/www.5gplc.com\/products\/emerson-pr6424-003-030-con021-eddy-current-sensor-system","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
