Factory linear calibration establishes a sensitivity factor of 8 V\/mm (203.2 mV\/mil) across its +\/- 1.0 mm linear measurement envelope when targeted against conductive steel shafts. Proper mechanical installation demands gap voltage validation, establishing a static DC bias at -10 VDC at the mid-scale operational point to preserve linear range symmetry for rotor dynamics monitoring. To eliminate electromagnetic mutual coupling and ensure cross-talk suppression, adjacent 12.5 mm probe tips require a minimum axial clearance distance of 30 mm, with radial clearance from surrounding metallic housings maintained beyond 20 mm from the central axis of the tip.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How is the static gap voltage zeroed during field installation?\u003c\/p\u003e\n\u003cp\u003eA: Advance the probe body into the mechanical housing while measuring the raw DC voltage output across the signal conditioner module terminals. Adjust physical probe depth until the signal output registers -10 VDC (the nominal mid-span operational point), then secure the mounting jam nut.\u003c\/p\u003e\n\u003cp\u003eQ: Can the integrated cable on the PR6453\/110-101 be cut or field-spliced?\u003c\/p\u003e\n\u003cp\u003eA: No. Splicing or trimming the integral cable alters total system capacitance and inductance, invalidating the 8 V\/mm scale factor calibration and causing measurement errors.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eInspect the 12.5 mm tip and stainless steel threaded body for structural damage, contamination, or metal debris prior to mounting.\u003c\/li\u003e\n\u003cli\u003eConfirm that the housing thread tapping is clean, clear of burrs, and matches the sensor body thread pitch.\u003c\/li\u003e\n\u003cli\u003eVerify radial mechanical clearance of at least 20 mm around the sensing tip to prevent false electrical loading from adjacent housing walls.\u003c\/li\u003e\n\u003cli\u003eCarefully thread the probe into position while taking real-time DC gap voltage measurements at the driver unit terminals.\u003c\/li\u003e\n\u003cli\u003eOnce the target gap voltage (-10 VDC nominal mid-span) is established, tighten the outer jam nut to a maximum torque of 15 Nm without allowing the sensor body to rotate.\u003c\/li\u003e\n\u003cli\u003eRoute the high-temperature integral cable away from high-voltage AC motor lines, variable frequency drives, and thermal sources exceeding +180 deg C.\u003c\/li\u003e\n\u003cli\u003eTerminate all field wiring inside IP-rated junction boxes, grounding the cable shield drain wire exclusively at the monitoring system rack cabinet end.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Emerson Epro","offers":[{"title":"Default Title","offer_id":45510143606899,"sku":"PR6453-110-101","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/CON021_PR6423002-001-CN_1_a722b381-2030-45b8-8e05-b95fee1438f6.jpg?v=1789630025","url":"https:\/\/www.dcssupplier.com\/products\/epro-pr6453-110-101-12-5-mm-eddy-current-sensor","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
