Features:

  • Integrated Design Direct-Wiring Proximity Measurement System
  • Advanced Glass-Filled PPS Polymer Enclosure for Harsh Operating Environments
  • External Probe Adjustment Capabilities Compatible with Legacy Housing Footprints
The Bently Nevada 330881-16-11-165-07-02 PROXPAC XL Proximity Transducer Assembly functions as a completely self-contained proximity sensor system, delivering precise dynamic vibration and shaft position measurements. It integrates an internal 3300 XL Proximitor sensor directly into its housing cover, continuously processing eddy current signals without requiring an external extension cable. Field wiring runs straight from the machinery monitor to the assembly, effectively eliminating intermediate cabling and separate Proximitor junction boxes. This streamlined architecture offers significant improvements over conventional probe setups while retaining the external gap adjustment features of traditional 31000 and 32000 probe housing designs.

The PROXPAC XL housing provides robust mechanical protection for sensitive internal transducer components and is built for demanding industrial locations. Molded from Polyphenylene Sulfide (PPS)—an advanced thermoplastic embedded with glass and conductive fibers—it delivers high structural strength while dissipating static electric charges. The housing is rated for Type 4X and IP66 ingress protection, safeguarding the internal electronics from moisture, dust, and corrosive severe environments. Replacing standard metallic enclosures, this lightweight composite structure resists environmental degradation across critical machinery monitoring applications.

For exact mechanical fitting and system integration, the 330881-16-11-165-07-02 configuration provides tailored physical specifications. It incorporates a 3300 XL 8 mm proximity probe without approvals (-16), an 11 mm standoff adapter (-11), and a 165 mm probe penetration length (-165) to achieve correct tip positioning near the shaft surface. Cable entry and mounting are accommodated through one PG21 x M20 fitting with two plugs (-07) alongside a 3/4-14 NPT mounting thread (-02). During system design or hardware retrofits, these parameters ensure proper installation, secure sealing, and immediate signal continuity back to the central monitoring rack.

The 330881-16-11-165-07-02 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).

  • Vibration and Displacement Analysis: Continuously tracks dynamic radial vibration and axial position changes on fluid-film bearing machines.
  • Shaft Position Monitoring: Delivers exact, non-contact measurements of structural shaft displacement, expansion, and thrust behavior.
  • Speed and Keyphasor Phase Reference: Monitors rotating shaft speeds or provides a phase reference signal (Keyphasor) for diagnostic timing.
  • Harsh Outdoor and Industrial Environments: Deployed across oil & gas refineries, power generation plants, and wastewater facilities where the sensor must survive extreme contamination.
  • No Extension Cable Required: Unlike standard installations, the internal 3300 XL 8 mm probe connects directly to the integrated Proximitor sensor module in the housing cover, avoiding external extension cables and their potential failure points.
  • Field Monitor Systems: Interoperates directly via field wiring with mainstream industrial monitoring networks, specifically the Bently Nevada 3500 Series Machinery Protection System and Orbit60 platforms.
  • Backward Footprint Interoperability: Serves as a direct mechanical drop-in replacement for the older Bently Nevada 31000 and 32000 Proximity Probe Housing Assemblies, mirroring their footprint while replacing steel/aluminum with robust composites.
  • Housing Engineering: Built from Polyphenylene Sulfide (PPS) molded with conductive glass fibers. This specialized composite shrugs off chemical degradation, maximizes mechanical strength, and dissipates dangerous static charges.
  • Environmental Sealing: Rated IP66 and Type 4X. It protects internal components from severe weather, dust, and hose-directed water blasts.
  • Process Containment: Features internal Viton O-rings around the probe case and a Neoprene O-ring on the sleeve to seal against minor process differential pressures.
  • Direct-to-Monitor Wiring: Field conductors bypass independent junction boxes and connect cleanly via integrated SpringLoc terminals tucked under the housing cover.
Description
The Bently Nevada 330881-16-11-165-07-02 PROXPAC XL Proximity Transducer Assembly is specifically designed to handle the complex challenges of vibration monitoring and shaft position measurement in harsh industrial rotating machinery. In traditional probe installations, engineers faced signal loss, cable damage, and space constraints caused by long extension cables running between the probe housing and a separate Proximitor sensor enclosure. The Bently Nevada 330881-16-11-165-07-02 solves this fundamental issue by integrating its own 3300 XL Proximitor sensor directly inside the housing cover. This self-contained, all-in-one design completely eliminates the need for an extension cable between the probe and its sensor, as well as the requirement for a standalone Proximitor junction box, allowing field wiring to connect directly between the machinery monitor and the 330881-16-11-165-07-02 assembly.

Sharing the proven mechanical advantages of legacy 31000 and 32000 probe housing assemblies, the Bently Nevada 330881-16-11-165-07-02 allows operators to safely access and externally adjust proximity probe gaps without dismantling machine casings. Built for severe operating conditions across heavy industries—such as oil and gas refining, power generation, petrochemical processing, and heavy manufacturing—the housing is constructed from advanced Polyphenylene Sulfide (PPS) molded thermoplastic reinforced with glass and conductive fibers. This composite material replaces conventional steel and aluminum housings to deliver enhanced mechanical strength and effective electrostatic charge dissipation. Rated for Type 4X and IP66 ingress protection, the 330881-16-11-165-07-02 safeguards sensitive internal sensing components against extreme moisture, dust, and corrosive outdoor environments.
