Specifically engineered for the 3300 XL series, this housing assembly integrates the probe and Proximitor sensor into a single, robust enclosure. It effectively shields sensitive instrumentation from harsh industrial environments, including oil mist, moisture, and mechanical impact. In critical turbomachinery applications—such as steam turbines, centrifugal compressors, and large motors—the Proxpac XL ensures signal integrity and extends the lifespan of vibration monitoring hardware. By consolidating components, it simplifies field wiring and reduces potential failure points in the Turbine Supervisory Instrumentation (TSI) loop.\u003c\/p\u003e\n\u003ch2\u003eModel Suffix Analysis\u003c\/h2\u003e\n\u003cp\u003eThe 330881-28-07-155-03-02 configuration defines specific physical and environmental adaptations for demanding field installations.\u003c\/p\u003e\n\u003ch3\u003eHousing Option (-28)\u003c\/h3\u003e\n\u003cp\u003eSpecifies a 3\/4-14 NPT conduit fitting with a high-durability aluminum body, providing superior EMI\/RFI shielding and corrosion resistance.\u003c\/p\u003e\n\u003ch3\u003eProbe Option (-07)\u003c\/h3\u003e\n\u003cp\u003eDesigned for the 3300 XL 8mm Proximity Probe with a 3\/8-24 UNF thread, optimized for standard displacement and vibration measurements.\u003c\/p\u003e\n\u003ch3\u003eStandoff Adapter Length (-155)\u003c\/h3\u003e\n\u003cp\u003eIndicates a 15.5-inch standoff length, allowing the probe to penetrate deep machine casings or insulation layers while maintaining a secure external mounting point.\u003c\/p\u003e\n\u003ch3\u003eProbe Penetration (-03)\u003c\/h3\u003e\n\u003cp\u003eDetermines the internal reach of the probe tip, ensuring precise gap voltage settings relative to the target shaft surface.\u003c\/p\u003e\n\u003ch3\u003eMounting Thread Option (-02)\u003c\/h3\u003e\n\u003cp\u003eStandardized mounting threads for secure mechanical anchoring to the machine bearing housing or casing.\u003c\/p\u003e\n\u003ch2\u003eHardware Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr class=\"firstRow\"\u003e\n\u003ctd\u003e\u003cstrong\u003eFeature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eTechnical Data\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eManufacturer\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eBently Nevada (Baker Hughes)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003ePart Number\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e330881-28-07-155-03-02\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eCompatibility\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e3300 XL 8mm Proximity Systems\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eMaterial\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eAnodized Aluminum \/ Stainless Steel Components\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eTemperature Range\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e-51°C to +177°C (-60°F to +350°F)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eIngress Protection\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eIP66 \/ NEMA 4X Equivalent\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eWeight\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eApprox. 3.2 kg (7.05 lbs)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eCountry of Origin\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eUSA\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eHS Code\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e90318080\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eField Installation Guidelines\u003c\/h2\u003e\n\u003cp\u003eEngineers must verify the Standoff Adapter length against the machine casing thickness before installation. Ensure the O-ring seals are lubricated with system-compatible oil to maintain the IP rating. During the gapping process, use a calibrated voltmeter to monitor the Proximitor output; typically, a -10.00 Vdc bias indicates the center of the linear range for 3300 XL 8mm probes. Maintain a minimum cable bend radius of 25.4mm (1 inch) within the housing to prevent signal attenuation or mechanical fatigue of the coaxial cable.\u003c\/p\u003e\n\u003ch2\u003eOperational Excellence\u003c\/h2\u003e\n\u003cp\u003eThe Proxpac XL series eliminates the need for separate Proximitor housings, significantly reducing the footprint required for instrumentation. Its thermal stability ensures that expansion or contraction of the standoff adapter does not introduce artificial \"DC shift\" in vibration data. This housing is indispensable for plants operating under API 670 standards, providing the mechanical rigidity necessary for high-fidelity data acquisition in catastrophic failure prevention systems.\u003c\/p\u003e\n\u003ch2\u003eLogistics and Handling\u003c\/h2\u003e\n\u003cp\u003eDelivery time: 3-5 days when payment finish, BY DHL\/FEDEX\/UPS.\u003c\/p\u003e\n\u003cp\u003eAll units are shipped in original anti-static industrial packaging with factory-sealed moisture barriers.

Using non-XL probes may require different cable adapters and could impact the total electrical length calibration.\u003c\/p\u003e\n\u003cp\u003eQ2: How does the -155 suffix impact the installation depth?\u003c\/p\u003e\n\u003cp\u003eA2: The 155 represents a 15.5-inch standoff. This must be matched with the probe's total length and the \"Probe Penetration\" suffix to ensure the tip reaches the target shaft within its linear range.\u003c\/p\u003e\n\u003cp\u003eQ3: Is the housing explosion-proof?\u003c\/p\u003e\n\u003cp\u003eA3: The 330881 series is designed to meet various North American (CSA) and International (ATEX\/IECEx) standards for hazardous areas when installed with appropriate conduits and seals.
