Product Description
330880-16-00-021-03-02 Bently Nevada Self-contained Proximity Transducer Assembly
Product Overview

Designed for seamless integration in critical machinery monitoring, the Bently Nevada 330880-16-00-021-03-02 PROXPAC XL is engineered for highly corrosive and electrically active environments. This advanced system features a revolutionary glass-reinforced Polyphenylene Sulfide (PPS) thermoplastic housing with integrated electrostatic dissipation.

The PROXPAC XL directly eliminates the need for separate Proximitor housings and extension cables by integrating a full 3300 XL Proximitor sensor right inside its weatherproof cover. With a compact 2.1-inch penetration depth and factory-supplied NPT fittings, it provides the ultimate standalone, self-contained solution for precise radial vibration and axial position monitoring on high-speed pumps, fans, and compressors.

Key Features & Benefits
  • Integrated Sensor Design: Built-in 3300 XL Proximitor inside the PPS cover

    Completely cuts out the need to buy, route, and troubleshoot expensive external extension cables or separate sensor enclosures. Field wiring links directly from your machine monitor to the PROXPAC assembly, slicing your total installation time and component footprint in half.

  • Housing Material: Molded Glass-reinforced Polyphenylene Sulfide (PPS)

    Replaces traditional heavy metal or aluminum enclosures with high-strength, non-corrosive thermoplastic embedded with conductive fibers. This design continuously drains away stray electrostatic charges and completely shields internal signals from heavy plant EMI.

  • Fittings Option: 03 Kit (Includes Reducer & Plugs)

    Delivers a pre-packaged hardware adaptation kit with stainless steel reducers right out of the box. It lets installers bridge different conduit thread sizes seamlessly without stopping the job to search for specialized industrial adapters.

Engineer's Note
"Our application group heavily favors the Bently Nevada 330880-16-00-021-03-02 for shallow machine casings because its 2.1-inch probe depth provides high structural rigidity with near-zero shaft deflection errors. Since the Proximitor sensor is internal, you can run up to 300 meters of standard twisted-shielded field wiring directly out of the IP66-rated housing to your main monitoring rack. When buttoning up the cover, verify that the integrated O-ring is fully seated to preserve the Type 4X waterproof barrier against high-pressure washdowns."
Frequently Asked Questions
Do I need to buy a separate extension cable to connect the internal probe to the system?

No. The PROXPAC XL is entirely self-contained. The internal probe connects directly to the built-in Proximitor sensor module situated inside the housing dome, completely dropping the need for an external extension cable run.

What type of machine targets can this 8mm probe system accurately track?

This assembly utilizes a standard 3300 XL 8mm probe tip requiring a minimum flat target diameter of 15.2 mm (0.6 in). It is highly recommended for steel shafts with a diameter of 76.2 mm (3.0 in) or larger to ensure optimal eddy-current linearity.

Can this '16' option code model be used in explosion-proof hazardous zones?

The '16' suffix dictates that this specific assembly does not carry official North American or European regional hazardous area approvals. If your refinery or plant site demands certified safe operation in explosive gas zones, you will need to order the '28' option variant which includes multiple CSA, ATEX, and IECEx certifications.

Application Case Study
Wastewater Treatment Plant Aeration Blower Station (Texas, USA)

Operating Conditions: High atmospheric humidity, exposure to ambient chlorine/corrosive vapors, and continuous operation.

Performance Record: This exact 2.1-inch unarmored PROXPAC XL housing was integrated directly into the bearing housings of critical aeration blowers. While neighboring aluminum housings suffered from chemical pitting, the advanced PPS composite body remained immune to corrosion over years of exposure. Because it eliminated separate terminal boxes outside the blower skin, maintenance crews were able to run calibration tests directly at the machine face, saving hours of downtime.
