The sensor generates high-frequency electromagnetic fields at the probe tip to observe relative metal surface distance without physical contact. Coupled with external signal processing modules via an 8.0 m integral cable, the transducer assembly converts mechanical motion into linear voltage signals across dynamic turbomachinery loops.\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\/000-131\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eEmerson \/ EPRO\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eGermany\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003eStandard Probe Assembly (0.40 kg typical)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eStandard Threaded Body Profile\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 to +45 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003ePowered via external CON021 signal converter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLinear Range\u003c\/td\u003e\n\u003ctd\u003e2 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInitial Air Gap\u003c\/td\u003e\n\u003ctd\u003e0.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCable Length\u003c\/td\u003e\n\u003ctd\u003e8.0 m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccuracy\u003c\/td\u003e\n\u003ctd\u003e+\/- 0.025 mm DSL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem 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\u003eThe Emerson PR6423\/000-131 transducer path interfaces directly with signal conversion hardware utilizing channel-to-channel isolation to prevent electrical ground loops in high-density rack cabinets. When integrated into 4-20 mA HART loop protocol architectures, the secondary transmitter module overlays digital diagnostic metadata onto the analog measurement signal without interrupting real-time vibration tracking. Internal signal filtering suppresses external electromagnetic interference, maintaining precise linear scaling across variable machine speeds and continuous operating cycles.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does the 0.5 mm initial air gap setting affect measurement accuracy during mechanical setup?\u003c\/p\u003e\n\u003cp\u003eA: Setting the probe at the specified 0.5 mm initial air gap establishes the physical center of the 2 mm linear measurement range. This positioning ensures the output voltage remains within calibrated tolerances during both positive and negative shaft deflections.\u003c\/p\u003e\n\u003cp\u003eQ: What grounding precautions must technicians take for the 8.0 m integrated cable?\u003c\/p\u003e\n\u003cp\u003eA: Engineers must ground the cable shield at a single point at the terminal cabinet end. Grounding both ends creates loop currents that introduce electrical noise into the millivolt-level probe signal.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eMount the PR6423\/000-131 securely using counter-nut hardware to maintain stable positioning against machine casing vibration. Maintain clean radial clearance around the probe tip to eliminate side-wall interference from adjacent metallic surfaces. Verify the probe gap voltage using a calibrated multimeter before final tightening to ensure the transducer operates inside its linear voltage response curve.\u003c\/p\u003e\n\u003cp\u003eRoute the 8.0 m integral cable through dedicated protective conduit away from high-voltage motor power wiring. Keep a minimum bending radius of 35 mm along the cable run to prevent internal coaxial conductor degradation. Torque all threaded conduit fittings to establish at least 5 thread engagements for reliable mechanical enclosure integrity.\u003c\/p\u003e","brand":"EPRO","offers":[{"title":"Default Title","offer_id":51222167617848,"sku":"PR6423\/000-131","price":256.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0893\/1616\/3896\/files\/PR6426010-1301.jpg?v=1760060003","url":"https:\/\/www.automodulexpert.com\/products\/eddy-current-displacement-sensor-emerson-epro-pr6423-000-131","provider":"AutoModuleXpert Ltd.","version":"1.0","type":"link"}
