Variations in cable length or capacitance directly alter the tuned LC circuit frequency of the Proximitor sensor, corrupting scale factor accuracy.\u003c\/p\u003e\n\u003cp\u003eDuring installation and maintenance, technicians perform gap voltage validation (-10 VDC targets at center gap position) across the signal lead and shield. The flexible stainless steel armor delivers high mechanical crushing protection while preventing cross-talk suppression degradation caused by parasitic capacitive coupling in dense cable runs.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the stainless steel armor of the 330730-040-01-00 cable be grounded at both ends?\u003c\/p\u003e\n\u003cp\u003eA: No. The extension cable armor and inner coaxial shield must remain electrically isolated from machine earth at the probe end. Grounding must be established exclusively at the Proximitor sensor housing to eliminate ground loops that introduce 50\/60 Hz line noise.\u003c\/p\u003e\n\u003cp\u003eQ: How does the -01 armored option affect the physical bend radius compared to standard non-armored cables?\u003c\/p\u003e\n\u003cp\u003eA: The stainless steel armor increases the minimum dynamic bend radius requirement to 38.1 mm (1.5 in). Bending the cable beyond this limit risks buckling the inner coaxial sheath and altering physical conductor geometry.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eInspect the 330730 extension cable for mechanical sheath cuts, crushed armor sections, or moisture ingress before mounting.\u003c\/li\u003e\n\u003cli\u003eRoute the cable through protective cable trays or conduit, maintaining a minimum bend radius of 38.1 mm (1.5 in) along the armor run.\u003c\/li\u003e\n\u003cli\u003eKeep the extension cable separated from high-voltage motor feeds and variable frequency drive output cables by a minimum clearance of 300 mm to avoid electromagnetic interference.\u003c\/li\u003e\n\u003cli\u003eMate the ClickLock miniature coaxial connectors until a firm click is felt; tighten the threaded coupling finger-tight plus 1\/8 turn. Do not apply heavy pliers or over-torque tools.\u003c\/li\u003e\n\u003cli\u003eVerify that gap voltage validation yields approximately -10.0 VDC across the Proximitor output terminals when the target shaft rests at mid-span journal clearance.\u003c\/li\u003e\n\u003cli\u003eTerminate the overall drain shield wire strictly at the instrument system earth point at the Proximitor sensor enclosure.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":43681173667930,"sku":"330730-040-01-00","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/330130-040-00-00_3a8da0dd-1630-425f-b889-ed8a6ed597a0.png?v=1784517531","url":"https:\/\/www.spareoil.com\/products\/330730-040-01-00-bently-nevada-3300-xl-11-mm-extension-cable","provider":"SpareOil Automation","version":"1.0","type":"link"}
