Driven through an external CON-series signal converter, the system provides accurate distance outputs over conductive metallic surfaces. Proper installation requires gap voltage validation during physical alignment, positioning the static DC bias voltage at -10 VDC to establish the mid-span operational point within the linear measurement envelope. To limit mutual electromagnetic interference and maintain cross-talk suppression, adjacent probe tips must maintain a minimum central axis spacing of 25 mm, while providing at least 15 mm radial clearance from surrounding metallic machine housing walls.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How is the physical gap zeroed during mechanical positioning?\u003c\/p\u003e\n\u003cp\u003eA: Thread the sensor body into the mounting frame while monitoring the raw DC output voltage across the signal converter terminals. Adjust probe depth until the signal output reads -10 VDC, then secure the mounting jam nut.\u003c\/p\u003e\n\u003cp\u003eQ: Can the integral probe cable on the PR6426-010-000 be trimmed or spliced in the field?\u003c\/p\u003e\n\u003cp\u003eA: No. Cutting or field-splicing the integral cable alters internal system inductance and capacitance, invalidating factory calibration curves and producing measurement errors.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eInspect the PEEK tip and stainless steel threaded casing for mechanical flaws, contamination, or thread damage prior to insertion.\u003c\/li\u003e\n\u003cli\u003eConfirm the mounting bracket tapping is clean, burr-free, and correctly aligned with the target surface.\u003c\/li\u003e\n\u003cli\u003eMaintain a minimum radial clearance of 15 mm surrounding the PEEK tip to prevent false side-loading effects from adjacent metal structures.\u003c\/li\u003e\n\u003cli\u003eCarefully thread the probe into position, monitoring real-time DC gap voltage readings at the driver converter terminals during insertion.\u003c\/li\u003e\n\u003cli\u003eLock the outer jam nut to a maximum torque of 12 Nm once the target -10 VDC static gap voltage is established, ensuring the probe casing does not rotate.\u003c\/li\u003e\n\u003cli\u003eRoute the integral cable inside grounded metal conduit, keeping it physically isolated from high-power AC lines and variable frequency drive cables.\u003c\/li\u003e\n\u003cli\u003eTerminate all field wiring inside IP-rated junction enclosures, grounding the cable shield drain wire at the main system cabinet frame end only.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Emerson Epro","offers":[{"title":"Default Title","offer_id":45510145540211,"sku":"PR6426-010-000","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/PR9376-010-011_2_53a855b2-8984-4312-8561-b6e54eab16ea.png?v=1789629983","url":"https:\/\/www.dcssupplier.com\/ar\/products\/epro-pr6426-010-000-current-sensor","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
