During field installation loops, engineers manipulate the external threaded barrel section to alter the sensor gap clearance, allowing precise target capture. Adjusting this external housing sleeve allows technical personnel to secure the necessary gap voltage validation target (-10 VDC targets) on the internal driver modules without exposing personnel or electronics to running rotor dynamics elements, while the structural metal shielding ensures cross-talk suppression between radial measuring channels.\u003c\/p\u003e\n\u003ch3\u003eLogistics Kit Manifest\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eOne (1) Bently Nevada 21000-00-00-00-00-02 aluminum housing structure\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eOne (1) Internal O-ring fluid-barrier sealing kit\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eOne (1) Threaded locknut and adjustment washer combination pack\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eTechnical certification manual specifying standard safety classification metrics\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eMechanical Installation and Sealing Guidelines\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eVerify that the primary machine casing receiving port is clean and free of burrs before threading the housing body into position.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eThread the housing base assembly into the machine casing wall using a minimum of 5 full NPT thread engagements to satisfy standard environmental sealing constraints.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSecure the internal proximity probe within the housing bore sleeve, passing the integrated cable lead through the internal guiding channels.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eConnect a calibrated digital voltmeter to the corresponding Proximitor test points to monitor output voltages while adjusting the external thread layout.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eRotate the housing adjustment assembly until reaching the standardized -10 VDC gap validation coordinate, then lock the hex locknut to 11.3 N-m to freeze mechanical motion.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eLogistics Packaging \u0026amp; Dispatch Protocol\u003c\/h3\u003e\n\u003cp\u003eDelivery time: 3-5 days when payment finish, with all shipping routed via premium global carriers including DHL, FEDEX, or UPS. The mechanical housing assemblies are enclosed inside high-durability vapor-barrier anti-static industrial packaging blocks to prevent oxidation of the threaded interfaces and machined aluminum seats. Master packing containers feature multi-layered high-density molded polyurethane foam structures to insulate the physical tolerances and thread paths from kinetic distortion during international transport lines.\u003c\/p\u003e\n\u003ch3\u003eTechnical Engineering FAQ\u003c\/h3\u003e\n\u003cp\u003eQ: Can an engineer replace or adjust the internal proximity probe without removing this 21000 series housing from the machine case?\u003c\/p\u003e\n\u003cp\u003eA: Yes. The 21000 series architecture allows the external rear cap to be unthreaded, enabling direct extraction or installation of the internal probe element without breaking the primary NPT process seal on the machine casing wall.\u003c\/p\u003e\n\u003cp\u003eQ: What failure condition arises if the internal process fluid O-ring seal degrades over time?\u003c\/p\u003e\n\u003cp\u003eA: O-ring degradation allows process oils or vapors to migrate into the housing sleeve cavity. While this does not cause immediate mechanical damage to the housing, oil pooling around the probe cable connections can distort loop capacitance, causing errors during gap voltage validation.\u003c\/p\u003e\n\u003cp\u003eQ: Is this specific housing assembly compatible with armored proximity probe options?\u003c\/p\u003e\n\u003cp\u003eA: No. The internal guide channels and cable clearance tolerances of this model are configured for non-armored standard coaxial probe cables with ClickLoc interfaces. Armored cables require a larger internal bore geometry to prevent binding during physical adjustment loops.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":45518822834349,"sku":"21000-00-00-00-00-02","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/bently-nevada-21000-00-00-00-00-02-proximity-probe-housing-assemblies-gwjknghjyfd.jpg?v=1766979604","url":"https:\/\/www.maxwellplc.com\/products\/21000-00-00-00-00-02-bently-nevada-21000-series-proximity-probe-housing","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
