Gap‑voltage validation follows the standard −10 VDC target, ensuring linear displacement behavior across the 2.0 mm measuring span. The 50 Ω output impedance stabilizes signal transmission over field cable lengths up to 305 m, suppressing phase distortion during rotor‑dynamic analysis. Cross‑talk suppression is achieved through internal shielding and matched impedance paths, allowing multi‑probe installations around large shafts without channel interference.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the transducer be removed while the Proximitor remains energized? A: Removal should occur only when the channel is de‑energized to avoid transient gap‑voltage excursions.\u003c\/p\u003e\n\u003cp\u003eQ: Does the 50 mm penetration depth require recalibration? A: No. Penetration depth is mechanically defined; electrical calibration is governed by the probe\/Proximitor pairing.\u003c\/p\u003e\n\u003cp\u003eQ: How does long‑distance cabling affect frequency response? A: The assembly supports up to 305 m of field cable; attenuation remains within the specified 0 Hz to 10 kHz band.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMaintain a clean mounting surface to ensure stable eddy‑current field alignment.\u003c\/li\u003e\n\u003cli\u003eVerify 3\/4‑14 NPT thread engagement to avoid mechanical drift under vibration.\u003c\/li\u003e\n\u003cli\u003eGround shielding at the Proximitor end only to prevent ground‑loop formation.\u003c\/li\u003e\n\u003cli\u003eAvoid sharp cable bends to preserve coaxial impedance.\u003c\/li\u003e\n\u003cli\u003eConfirm recommended 1.27 mm gap before energizing the monitoring channel.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":44115596607562,"sku":"330881-28-00-050-03-02","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_1.png?v=1751868862","url":"https:\/\/www.topbrandsplc.com\/products\/bently-nevada-330881-28-00-050-03-02-proxpac-xl-proximity-transducer","provider":"Topbrands PLC Limited","version":"1.0","type":"link"}
