System length matching maintains exact signal phase velocity essential for high-speed rotor dynamics tracking and phase angle calculations.\u003c\/p\u003e\n\u003cp\u003eDuring installation and field verification, gap voltage validation targets a nominal -10 VDC reading at the Proximitor output terminals when the probe target resides within the linear measurement band. The protective armor and outer connector sleeve eliminate environmental contamination and maintain cross-talk suppression along dense cable trays.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the addition of the connector protector (-03 option) change the electrical installation requirements?\u003c\/p\u003e\n\u003cp\u003eA: No. The connector protector provides physical shielding against environmental contaminants and oil, but electrical isolation requirements remain identical. The shield must be floating at the probe end and tied to earth ground only at the Proximitor sensor housing.\u003c\/p\u003e\n\u003cp\u003eQ: Can the cable length be trimmed in the field if 4.0 m is longer than required?\u003c\/p\u003e\n\u003cp\u003eA: No. Trimming or altering the cable length alters overall system resistance and capacitance, which invalidates factory calibration and induces scale factor errors into displacement and vibration measurements.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eInspect the cable FEP outer jacket, armor, and connector seals for cuts or mechanical damage prior to mounting.\u003c\/li\u003e\n\u003cli\u003eRoute the armored cable through designated instrument raceways, maintaining a minimum static bend radius of 38.1 mm (1.5 in).\u003c\/li\u003e\n\u003cli\u003eEnsure a minimum clearance distance of 300 mm from power lines and VFD field wiring to eliminate inductive noise coupling.\u003c\/li\u003e\n\u003cli\u003eJoin the coaxial connectors securely until the locking mechanism fully seats; slide the integrated connector protector over the junction to seal out moisture and fluids.\u003c\/li\u003e\n\u003cli\u003eVerify gap voltage validation by measuring DC bias at the Proximitor sensor terminals; verify the reading approaches -10.0 VDC at mid-span mechanical gap.\u003c\/li\u003e\n\u003cli\u003eConnect the cable shield exclusively to system instrument ground at the Proximitor enclosure, ensuring no ground paths are formed at the probe junction.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":43681183596634,"sku":"330730-040-03-00","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/330101-37-57-10-02-051_c9b8fa00-6b68-41ff-892d-e39e8d3b54af.png?v=1784517747","url":"https:\/\/www.spareoil.com\/products\/bently-nevada-330730-040-03-00-3300-xl-11-mm-extension-cable","provider":"SpareOil Automation","version":"1.0","type":"link"}
