Features:

  • Direct Conduit Connection to Field Systems and External Probe Adjustment Capabilities
  • Integrates Advanced 3300 XL Proximitor Sensor into High-Durability PPS Enclosure
  • Designed for Hazardous Area Applications with International Approvals and 214 mm Penetration Depth
The Bently Nevada 330881-28-00-214-00-02 PROXPAC XL Proximity Transducer functions as an all-in-one proximity probe housing system, capturing non-contact shaft vibration and position measurements on rotating machinery. It directly converts probe-target proximity into proportional electrical signals without requiring an external extension cable, streaming dynamic data straight to associated machinery monitoring systems. Built with a Polyphenylene Sulfide (PPS) thermoplastic housing containing glass and conductive fibers, the 330881-28-00-214-00-02 provides extra structural strength, electrostatic charge dissipation, and Type 4X / IP66 environmental protection against harsh outdoor atmospheres.

The 330881-28-00-214-00-02 provides essential proximity sensing functions for critical machine monitoring, serving as a key hardware component that directly affects early fault detection on industrial turbines and pumps. Depending on the machine casing and mounting requirements, the transducer incorporates a 3300 XL 8 mm probe with a 214 mm penetration depth (-214) and 3/4-14 NPT threads (-02) for secure mounting through the machine wall. The housing design incorporates two plugs and two washers (-00) without additional fittings, occupying a compact physical footprint directly at the measurement point.

For applications requiring hazardous location compliance, the 330881-28-00-214-00-02 incorporates Multiple Approvals (-28) covering major international safety standards such as CSA, ATEX, and IECEx. In addition to eliminating extra Proximitor housing enclosures, the integrated design utilizes the cover as the active Proximitor sensor housing. Maintenance teams can manually calibrate or adjust the probe gap from the outside of the assembly without opening the housing, preserving internal seal integrity and avoiding exposure of internal electronics to aggressive environmental contaminants.

The 330881-28-00-214-00-02 Bently Nevada PROXPAC XL Proximity Transducer may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Radial Vibration Monitoring: Continuously tracks shaft dynamic displacement relative to fluid-film bearings to detect rotor unbalance, structural misalignment, or fluid-film instabilities.
  • Axial Position Tracking: Measures the static thrust movement of a shaft to prevent high-energy physical contact between rotating components and stationary internal machine casings.
  • Speed & Phase Reference: Observes once-per-turn timing marks on a shaft via a Keyphasor* setup to accurately calculate rotational speed and vibration phase angles.
  • Critical Asset Deployment: Routinely applied on high-stakes power-generation and oil-and-gas assets, such as steam turbines, centrifugal compressors, turbo-expanders, and heavy-duty pumps.
  • Integrated Proximitor Sensor: The housing cover natively contains the 3300 XL Proximitor sensor. This design choice completely eliminates the need for an external extension cable between the probe and the preamplifier.
  • Direct Field Wiring: Field instrumentation wiring connects directly from the monitor rack to the PROXPAC XL assembly, removing the requirement for a separate, remote Proximitor junction box.
  • SpringLoc Terminals:* Utilizes internal, spring-loaded wiring terminals that provide secure, highly vibration-resistant electrical connections without relying on traditional screw terminals.
  • Signal Output: Delivers a highly accurate analog output voltage directly proportional to the physical distance between the probe tip and the observed target surface.
  • Advanced Thermoplastic Housing: Constructed from Glass/Conductive Fiber-Molded Polyphenylene Sulfide (PPS). This material offers superior chemical resistance and structural strength while effectively dissipating electrostatic charges.
  • Severe Environment Protection: The housing holds robust environmental ratings, including NEMA Type 4X and an IP66 rating against aggressive dust and high-pressure water jets.
  • Exceptional Linear Accuracy: Engineered to measure small gaps with micro-level accuracy across a standard linear range of 0.25 mm to 2.3 mm (10 to 90 mils), maintaining an Incremental Scale Factor (ISF) of 7.87 V/mm (200 mV/mil).
  • Broad Frequency Response: Capable of measuring dynamic events from static DC up to 10 kHz, enabling precise tracking of both low-frequency thrust shifts and high-frequency machine vibrations.
Description
The Bently Nevada 330881-28-00-214-00-02 PROXPAC XL Proximity Transducer Assembly is a self-contained proximity probe housing system specifically engineered to simplify non-contact shaft vibration and position monitoring in demanding industrial environments. Constructed from Polyphenylene Sulfide (PPS) molded thermoplastic reinforced with glass and conductive fibers, the 330881-28-00-214-00-02 offers superior structural strength, electrostatic discharge protection, and severe-environment durability rated to Type 4X and IP66.

Designed specifically to solve the complexities of traditional proximity probe setups, the 330881-28-00-214-00-02 addresses the problem of signal degradation, cable failure, and high installation costs associated with separate components. By integrating the 3300 XL Proximitor sensor directly into its own housing cover, the 330881-28-00-214-00-02 completely eliminates the need for an extension cable between the probe and sensor, as well as the requirement for a separate Proximitor enclosure. This direct-wiring design resolves long-standing issues of field cable management, simplifies maintenance, and provides robust protection for critical vibration data on rotating machinery.

The 330881-28-00-214-00-02 is widely applied across heavy industrial sectors such as power generation, oil and gas, chemical processing, and water management. It is ideal for monitoring critical rotating equipment, including gas and steam turbines, centrifugal compressors, large industrial pumps, gearboxes, and electric motors operating in severe or hazardous outdoor environments. Its Multiple Approvals certification (-28) and Type 4X/IP66 ingress rating make the 330881-28-00-214-00-02 especially suitable for locations exposed to corrosive atmospheres, moisture, and high-pressure washdowns.
