transducer assembly that integrates a high-performance 3300 XL 8 mm probe within a ruggedized housing. \nThis system is a critical component of Turbine Supervisory Instrumentation (TSI), specifically developed for applications where standard probes require additional environmental protection. \nCommonly used in power generation, large-scale water treatment, and petrochemical processing facilities, the PROXPAC XL provides reliable non-contact displacement measurements for vibration and axial thrust monitoring. \nBy enabling external probe adjustment and replacement, the \u003cstrong\u003e330881-28-00-135-03-00\u003c\/strong\u003e reduces maintenance time and supports continuous operation of critical rotating equipment such as pumps, fans, and small

advantage of the PROXPAC XL housing compared with a standard probe installation?\u003c\/strong\u003e\u003cbr\u003e\nThe PROXPAC XL housing provides a robust environmental seal and mechanical protection for the probe lead. \nMore importantly, it allows the probe to be adjusted and replaced externally without removing machine covers, which significantly reduces maintenance time and operational downtime.\n\u003c\/p\u003e\n\n\u003cp\u003e\n\u003cstrong\u003eHow does the Multiple Approvals (Option 28) support international projects?\u003c\/strong\u003e\u003cbr\u003e\nOption 28 ensures the probe complies with intrinsic safety and explosion-proof standards including ATEX, IECEx, and North American CSA\/NRTL certifications. \nThis makes the \u003cstrong\u003e330881-28-00-135-03-00\u003c\/strong\u003e suitable for multinational installations and simplifies spare parts management across different regions.\n\u003c\/p\u003e\n\n\u003cp\u003e\n\u003cstrong\u003eCan the probe penetration be adjusted after manufacturing?\u003c\/strong\u003e\u003cbr\u003e\nThe 135 mm penetration depth is a fixed mechanical dimension of the internal sleeve and probe assembly. \nAlthough minor adjustment is possible through the mounting threads, the primary penetration length must be correctly specified during equipment selection to match the machine casing-to-shaft clearance.\n\u003c\/p\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\n\u003cul\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eGap Voltage Calibration:\u003c\/strong\u003e For radial vibration monitoring, set the probe gap near the center of the linear measurement range. \nConnect the probe to a powered Proximitor sensor and adjust the insertion depth until the DC output voltage is approximately -10 VDC. \nTighten the locking nut to 4.5 N·m (40 in-lb) to maintain a stable mechanical setting during operation.\n\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eEnvironmental Sealing:\u003c\/strong\u003e Use the M20 fitting and plugs supplied in the Option 03 kit to seal any unused ports in the PROXPAC housing. \nProper sealing prevents moisture, oil, and airborne contaminants from entering the enclosure and affecting signal reliability.\n\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eSide-Clearance Requirements:\u003c\/strong\u003e Maintain a minimum radial clearance of 13 mm (0.5 inches) between the probe tip and surrounding metal surfaces other than the target shaft. \nInsufficient clearance may result in side-viewing interference and inaccurate vibration measurements.\n\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eChemical Resistance:\u003c\/strong\u003e The probe tip is manufactured from Polyphenylene sulfide (PPS), which offers strong resistance to most industrial lubricants and fuels. \nVerify that any cleaning solvents used during maintenance are compatible with both PPS materials and the Viton O-rings used for pressure sealing.\n\u003c\/li\u003e\n\n\u003c\/ul\u003e","brand":"Bently Nevada","offers":[{"title":"Default
