Bently Nevada 330881-28-00-214-00-02 PROXPAC XL Proximity Transducer

Description

The 330881-28-00-214-00-02 is a metric PROXPAC XL Proximity Transducer assembly featuring an integrated 3300 XL 8 mm proximity probe configured with Multiple Approvals, a 214 mm probe penetration length, and a 3/4-14 NPT mounting thread. Unlike configuration options with standard unapproved probes, this specialized version integrates both the transducer probe and the Proximitor sensor into a single, self-contained plastic housing. This cohesive design eliminates the need for an intermediate extension cable, as well as a separate Proximitor sensor housing, allowing field wiring to connect directly from your monitoring system to the assembly cover.

Engineered for high durability in severe environments, the housing is molded from glass-reinforced, ultraviolet-resistant polyphenylene sulfide (PPS) thermoplastic. This advanced material incorporates conductive fibers to maximize mechanical strength while effectively dissipating electrostatic charges. Rated for Type 4X and IP66 conditions, this self-contained transducer system provides excellent resistance against moisture, dust, and corrosive industrial atmospheres, making it ideal for critical rotating machinery protection.

Features

• Direct Monitor Wiring: Self-contained assembly routes field connections directly to monitors, eliminating intermediate extension cables.
• Advanced PPS Thermoplastic: Glass-reinforced housing material offers high mechanical strength and effective electrostatic dissipation.
• Custom 214 mm Penetration: Precise C-dimension metric sleeve length of 214 mm accommodates deep-set mounting configurations.
• Environmental Protection: Certified for Type 4X and IP66 environments, ensuring seal integrity against hose-directed water.
• Flexible Adjustment: Threaded sleeve design allows plus-or-minus 12.7 mm of physical probe gap adjustment from the mid-setting point.
• Multiple Agency Approvals: Pre-certified under option 28 for cNRTLus, ATEX, and IECEx hazardous area applications.

Applications

• Continuous radial vibration and axial position tracking on steam turbines, gas turbines, and compressors.
• Industrial installations requiring simplified field wiring and reduced remote junction boxes.
• Machinery protection applications in highly corrosive, wet, or severe chemical process environments.
• High-density machinery arrays where space limitations prevent mounting separate Proximitor housings.

Installation Guidelines

• Grounding Protocol: Verify the integrated stainless steel grounding liner and retaining plate are connected properly to structural earth.
• Adjustment Range: Leverage the outer sleeve thread to perform final adjustments of up to plus-or-minus 12.7 mm from your target surface.
• Wiring Precautions: Seal conduit pathways carefully during commissioning to prevent moisture from traveling down field cables into the housing.
• Torque Requirements: Secure the retaining nut to a maximum of 29.5 N-m (260 in-lb), and the probe sleeve locknut to a maximum of 39.3 N-m (350 in-lb).
