Gap voltage validation targets a nominal -10 VDC baseline at 1.27 mm gapping to maintain a linear operational range. Cross-talk suppression protocols dictate a minimum 40 mm axial or 38 mm radial separation between adjacent probe tips, preserving signal clarity during rotor dynamics evaluations.\u003c\/p\u003e\n\u003ch3\u003eOrdering Information\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x 330881-16-04-138-03-02 PROXPAC XL assembly unit\u003c\/li\u003e\n\u003cli\u003e1 x 40 mm standoff adapter\u003c\/li\u003e\n\u003cli\u003e1 x M20 conduit fitting\u003c\/li\u003e\n\u003cli\u003e2 x Threaded enclosure sealing plugs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eProbe Gapping: Set the initial probe gap to 1.27 mm from the rotating target surface to center the output voltage within the linear operating curve.\u003c\/li\u003e\n\u003cli\u003eConduit Sealing: Secure the M20 conduit fitting using appropriate thread sealant to maintain the IP66 and Type 4X environmental protection rating.\u003c\/li\u003e\n\u003cli\u003eSpatial Separation: Keep adjacent probe tips separated by at least 40 mm for axial layouts or 38 mm for radial layouts to avoid electromagnetic cross-talk.\u003c\/li\u003e\n\u003cli\u003eEnclosure Grounding: Fasten the polyphenylene sulfide housing securely to machine earth ground to dissipate static charge buildup safely.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eWhat specific material is used for the PROXPAC XL housing construction?\u003c\/p\u003e\n\u003cp\u003eIt is manufactured from Polyphenylene Sulfide thermoplastic infused with glass and conductive fibers for electrostatic dissipation and environmental strength.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eHow does the 40 mm standoff adapter influence probe installation?\u003c\/p\u003e\n\u003cp\u003eIt provides the required mechanical extension length to clear thermal insulation barriers and mounting bosses on machine casings.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat is the target gapping value for the 8 mm probe system?\u003c\/p\u003e\n\u003cp\u003eThe probe should be gapped at approximately 1.27 mm, yielding a nominal output voltage of -10 VDC.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat conduit fitting is included with this specific part number configuration?\u003c\/p\u003e\n\u003cp\u003eThe unit includes one metric M20 fitting alongside two threaded sealing plugs for unused port entries.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhy is maintaining minimum probe separation important in multi-transducer setups?\u003c\/p\u003e\n\u003cp\u003eIt prevents high-frequency electromagnetic interference and cross-talk between adjacent eddy-current fields.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat is the primary function of the 138 mm penetration option?\u003c\/p\u003e\n\u003cp\u003eIt defines the exact insertion depth of the probe tip assembly relative to the exterior housing mounting face.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eDoes the transducer housing require an internal power supply connection?\u003c\/p\u003e\n\u003cp\u003eNo, power is supplied remotely through the external proximitor circuit connected to the internal sensor module.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat environmental protection rating does the assembled housing achieve?\u003c\/p\u003e\n\u003cp\u003eThe enclosure meets Type 4X and IP66 criteria, ensuring resistance against heavy moisture, dust, and washdowns.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":46026171187373,"sku":"330881-16-04-138-03-02","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/xianxian_09_0c678fd0-256c-4e5f-9d1d-6c16efaf092a.jpg?v=1783667684","url":"https:\/\/www.maxwellplc.com\/ga\/products\/330881-16-04-138-03-02-bently-nevada-3300-xl-proximity-transducers","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
