Gap voltage validation against -10 VDC targets ensures linear displacement behavior across the 2.0 mm measuring span. Internal shielding and impedance matching suppress cross-talk, enabling accurate rotor dynamics analysis in multi-probe installations.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the standoff adapter require recalibration? A: No, the adapter defines mechanical positioning only; electrical calibration remains governed by the probe\/Proximitor pairing.\u003c\/p\u003e\n\u003cp\u003eQ: Can the assembly be removed while energized? A: Removal should occur only when the monitoring channel is de-energized to avoid transient gap-voltage excursions.\u003c\/p\u003e\n\u003cp\u003eQ: How does long cable routing affect performance? A: The assembly supports extended cabling within specified limits; attenuation remains within the defined 0–10 kHz frequency response band.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eVerify 3\/4-14 NPT thread engagement to ensure mechanical stability under vibration.\u003c\/li\u003e\n\u003cli\u003eMaintain a clean mounting surface for consistent eddy-current field alignment.\u003c\/li\u003e\n\u003cli\u003eGround shielding at the Proximitor end only to prevent ground-loop formation.\u003c\/li\u003e\n\u003cli\u003eAvoid sharp bends in coaxial cabling to preserve impedance characteristics.\u003c\/li\u003e\n\u003cli\u003eConfirm recommended gap voltage before energizing the monitoring channel.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":44206926364746,"sku":"330881-28-05-050-03-02","price":1600.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/8569\/3770\/files\/32000-00-00-04-420-01-02_3.png?v=1751868862","url":"https:\/\/www.topbrandsplc.com\/products\/bently-nevada-330881-28-05-050-03-02-proxpac-xl-proximity-transducer-assembly","provider":"Topbrands PLC Limited","version":"1.0","type":"link"}
