When interfacing with plant monitoring networks operating 4-20 mA HART loop protocol transmitters or FOUNDATION Fieldbus nodes, the sensor maintains defined analog signal boundaries. Integrated thermal tracking preserves scale factor stability, minimizing offset drift to maintain accurate cold junction compensation and measurement integrity over the operational temperature range.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does the open cable end termination of the PR6423\/000-101 connect to downstream evaluation electronics?\u003c\/p\u003e\n\u003cp\u003eA: The flying leads connect directly to screw terminals or crimp connectors inside a field junction box or signal converter housing, requiring proper shield termination to prevent signal noise.\u003c\/p\u003e\n\u003cp\u003eQ: What is the effect of shortening the 4.0 m integrated cable during field installation?\u003c\/p\u003e\n\u003cp\u003eA: Trimming or splicing the 4.0 m integral cable changes the LC oscillator circuit characteristics, altering the calibrated 8 V\/mm scale factor and invalidating factory calibration.\u003c\/p\u003e\n\u003cp\u003eQ: How is the physical gap zeroed during mechanical installation?\u003c\/p\u003e\n\u003cp\u003eA: Position the probe head using precision feeler gauges or monitor the DC bias voltage at the signal converter to establish the target 0.5 mm initial air gap baseline.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eInspect the target rotor shaft area to verify the surface is free of mechanical scratches, rust, and magnetic runout.\u003c\/li\u003e\n\u003cli\u003eThread the 25 mm probe sleeve into the rigid mounting bracket perpendicular to the shaft centerline.\u003c\/li\u003e\n\u003cli\u003eAdjust insertion depth until reaching the 0.5 mm initial air gap setting using non-magnetic shims or static DC gap voltage verification.\u003c\/li\u003e\n\u003cli\u003eTorque the outer locknut to fixed installation specifications to prevent thermal or vibration loosening.\u003c\/li\u003e\n\u003cli\u003eExtend the 4.0 m open-ended cable to the local terminal housing without bending past the minimum bend radius.\u003c\/li\u003e\n\u003cli\u003eLand the open wire conductors onto the signal converter terminals, securing the cable outer shield to the cabinet single-point ground.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"EMERSON","offers":[{"title":"Default Title","offer_id":53446141575477,"sku":"PR6423\/000-101","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/PR6424000-010_be5f031b-2049-4b82-aa5d-7d715f691d83.png?v=1788341736","url":"https:\/\/www.5gplc.com\/products\/emerson-pr6423-000-101-epro-eddy-current-sensors","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
