Field calibration verification relies on gap voltage validation at the Proximitor sensor output, maintaining a target nominal bias near -10 VDC at the mechanical mid-span. Proper voltage targeting ensures linear response during dynamic rotor dynamics excursions, avoiding signal clipping under transient conditions. Correct coaxial cable routing and terminal shield isolation provide cross-talk suppression between neighboring sensor channels installed within the same bearing housing.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the primary function of the gap voltage verification step?\u003c\/p\u003e\n\u003cp\u003eA: Gap voltage verification ensures the probe tip is mechanically positioned within the linear center of its electrical measurement range, typically set to a -10 VDC bias output under static conditions.\u003c\/p\u003e\n\u003cp\u003eQ: Can the 5.0-meter integral cable be trimmed or spliced in the field?\u003c\/p\u003e\n\u003cp\u003eA: No. Trimming or splicing the cable alters the calibrated system capacitance and inductance, compromising the factory probe scaling accuracy.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eMount the probe housing into the machine casing thread, ensuring a minimum engagement of 5 full threads on the M14x1.5 body. Maintain an unthreaded clearance zone around the probe tip equal to at least two tip diameters to prevent metallic side-wall interference. Route the High Temperature FluidLoc cable through dedicated grounded conduit, keeping total bend radii above the minimum flexible cable allowance. Terminate cable shielding at a single system reference ground to avoid ground loop current interference.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":43681222787162,"sku":"330876-02-50-00-00","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/330101-00-08-05-02-00_274b3095-b185-49e1-baa4-1c1c8005fea1.png?v=1784526972","url":"https:\/\/www.spareoil.com\/products\/bently-nevada-330876-02-50-00-00-3300-xl-50-mm-proximity-probes","provider":"SpareOil Automation","version":"1.0","type":"link"}
