The probe housing permits external gap voltage validation, typically targeted to achieve a -10 VDC baseline setting. By utilizing the physical sleeve design, engineers can adjust the probe gap externally without shutting down the machinery or exposing the interior bearing housing. This design isolates the probe from hazardous atmospheres and process lubricants, suppressing cross-talk and high-frequency interference across adjacent channels while providing continuous rotor dynamics and axial position data.\u003c\/p\u003e\n\u003ch3\u003ePackage Bill of Materials\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Bently Nevada 31000-28-05-00-061-01-02 Housing Assembly\u003c\/li\u003e\n\u003cli\u003e1 x Pre-installed 3300 XL 8 mm Proximity Probe (0.5 m cable)\u003c\/li\u003e\n\u003cli\u003e1 x 3\/4-14 NPT explosion-proof conduit fitting\u003c\/li\u003e\n\u003cli\u003e2 x 3\/4-14 NPT pipe plugs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eMechanical Installation and Sleeve Insertion Rules\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eMachine Case Thread Mating\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEnsure the outer machine casing has a clean, tapped 3\/4-14 NPT mounting hole.
