By eliminating the necessity for a separate Proximitor sensor housing or an external extension cable, the 330881 system significantly simplifies industrial field installation, reduces wiring complexity, and forms a durable, self-contained eddy-current measurement system. The metric 330881 variant relies on metric conduit fittings (M20 or M25) and metric probe sleeve adjustments, distinguishing it from English-threaded 330880 models.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eOption 28 probe and approvals: Integrates a 3300 XL 8 mm proximity probe certified with multiple hazardous area approvals.\u003c\/li\u003e\n  \u003cli\u003eOption 04 standoff: Features a 40 mm standoff adapter to adjust probe positioning.\u003c\/li\u003e\n  \u003cli\u003eOption 70 penetration: Provides a 70 mm probe penetration depth.\u003c\/li\u003e\n  \u003cli\u003eOption 03 conduit fitting: Includes one M20 conduit fitting and two blanking plugs for secure cable routing.\u003c\/li\u003e\n  \u003cli\u003eOption 02 mounting thread: Uses a standard 3\/4-14 NPT mounting thread for standoff adapter engagement.\u003c\/li\u003e\n  \u003cli\u003eIntegrated Proximitor: Houses a 1-metre 3300 XL Proximitor sensor directly in the housing lid, eliminating separate extension cables.\u003c\/li\u003e\n  \u003cli\u003eAdvanced PPS housing: Molded glass-reinforced polyphenylene sulfide housing provides chemical resistance and static dissipation.\u003c\/li\u003e\n  \u003cli\u003eHigh environmental protection: Enclosure is rated for Type 4X and IP66 environments.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eUsed for non-contact shaft vibration and axial position measurements on rotating machinery.\u003c\/li\u003e\n  \u003cli\u003eIdeal for severe industrial environments including oil and gas facilities, petrochemical plants, and power generation turbines.\u003c\/li\u003e\n  \u003cli\u003eSimplifies installation in locations where mounting separate Proximitor sensors in external enclosures is impractical or costly.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eOrdering Information\u003c\/h3\u003e\n\u003ctable border=\"1\"\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eOption\u003c\/th\u003e\n      \u003cth\u003eCode on This SKU\u003c\/th\u003e\n      \u003cth\u003eDescription\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eOrderable Part Number\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003e\u003cstrong\u003e330881-28-04-70-03-02\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003ePROXPAC XL Proximity Transducer, Metric\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eA - Probe and Approvals Option\u003c\/td\u003e\n      \u003ctd\u003e28\u003c\/td\u003e\n      \u003ctd\u003e3300 XL 8 mm probe with Multiple Approvals\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eB - Standoff Adapter Option\u003c\/td\u003e\n      \u003ctd\u003e04\u003c\/td\u003e\n      \u003ctd\u003e40 mm standoff adapter length\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eC - Probe Penetration Option\u003c\/td\u003e\n      \u003ctd\u003e70\u003c\/td\u003e\n      \u003ctd\u003e70 mm probe penetration length\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eD - Fittings Option\u003c\/td\u003e\n      \u003ctd\u003e03\u003c\/td\u003e\n      \u003ctd\u003eOne M20 fitting, two plugs\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eE - Mounting Thread Option\u003c\/td\u003e\n      \u003ctd\u003e02\u003c\/td\u003e\n      \u003ctd\u003e3\/4-14 NPT mounting thread (required with standoff adapter)\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable border=\"1\"\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eManufacturer\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003eBently Nevada\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eModel \/ Part Number\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003e330881-28-04-70-03-02\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eTransducer Type\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003eMetric Integrated Proximity Transducer Assembly (PROXPAC XL)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eSensor Input\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003e3300 XL 8 mm Proximity Probe with 1-metre cable length (Option 28, multiple approvals)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003ePower Requirements\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003e-17.5 Vdc to -26 Vdc at 12 mA maximum without barriers;
