By housing the Proximitor directly at the measurement point, this assembly eliminates the need for a separate extension cable and external Proximitor enclosure, allowing field wiring to connect directly from the machinery monitor. The PPS plastic housing is glass- and conductive-fiber-reinforced to provide electrostatic charge dissipation and is rated for Type 4X and IP66 severe environments.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eOption 28 integrates a 3300 XL 8 mm proximity probe with multiple international hazardous area certifications (CSA, ATEX, IECEx).\u003c\/li\u003e\n  \u003cli\u003eOption 20 provides a 200 mm standoff adapter constructed of stainless steel.\u003c\/li\u003e\n  \u003cli\u003eOption 040 defines a 40 mm probe penetration depth for insertion into the machine casing.\u003c\/li\u003e\n  \u003cli\u003eOption 03 includes a single M20 fitting kit with two blanking plugs to seal unused conduit entries.\u003c\/li\u003e\n  \u003cli\u003eOption 02 provides a 3\/4-14 NPT mounting thread, which is required for the standoff adapter installation.\u003c\/li\u003e\n  \u003cli\u003eIntegrated Proximitor sensor design removes the need for high-frequency coaxial extension cables, reducing installation labor.\u003c\/li\u003e\n  \u003cli\u003ePolyphenylene Sulfide (PPS) housing construction offers high impact strength and resistance to corrosive process fluids.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cp\u003eThe PROXPAC XL assembly is used for non-contact shaft vibration and axial position measurements on rotating machinery such as steam turbines, gas turbines, compressors, pumps, and gearboxes.
