Scale factor is 7.87 V\/mm (200 mV\/mil), with linearity error less than ±0.06 mm across the range. Recommended gap voltage is −10 VDC, with operational spectrum between −2 VDC and −18 VDC. Cross-talk suppression and impedance matching are embedded to ensure stable displacement conversion in multi-probe installations.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions (FAQ)\u003c\/h3\u003e\n\u003cp\u003eQ: What is the recommended operating gap voltage? A: −10 VDC is the nominal operating center point, ensuring accurate displacement scaling.\u003c\/p\u003e\n\u003cp\u003eQ: What tensile strength limits apply to the probe cable? A: Maximum 330 N (75 lbf) from probe case to lead, and 270 N (60 lbf) at probe-to-extension cable interface.\u003c\/p\u003e\n\u003cp\u003eQ: Can the probe withstand high-pressure environments? A: Yes. The probe tip is evaluated to withstand up to 70 bar (1,000 psi) case-to-tip pressure differential.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eInstall probe tip perpendicular to the shaft surface for accurate displacement measurement.\u003c\/li\u003e\n\u003cli\u003eMaintain minimum cable bend radius of 25.4 mm (1.0 in) to prevent conductor fatigue.\u003c\/li\u003e\n\u003cli\u003eGround shielding at the monitoring rack end only to avoid ground loops.\u003c\/li\u003e\n\u003cli\u003eProtect connectors against condensation to maintain 100% humidity tolerance.\u003c\/li\u003e\n\u003cli\u003eVerify insertion depth to achieve −10 VDC gap reference during commissioning.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":44166766821450,"sku":"330192-00-68-05-05","price":850.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/8569\/3770\/files\/2_fc94afcd-4577-4329-8d60-0328df65fbde.jpg?v=1752033495","url":"https:\/\/www.topbrandsplc.com\/products\/330192-00-68-05-05-bently-nevada-eddy-current-proximity-probe","provider":"Topbrands PLC Limited","version":"1.0","type":"link"}
