PROXPAC XL Proximity Transducer | 330881-BR-04-034-06-02 | Bently Nevada

Technical Specifications

The Bently Nevada 330881-BR-04-034-06-02 is a PROXPAC XL Proximity Transducer for critical industrial rotating machinery such as large steam turbines, compressors, and fans. It is used for real-time monitoring of shaft vibration, shaft displacement, or speed/key phase signals.

Highly Self-Contained Integration: The 3300 XL preamplifier is directly integrated inside the housing end cap. This eliminates the need for costly coaxial extension cables in the field and a separate dedicated preamplifier junction box. The signal cable connects directly from the housing to the central monitoring frame, significantly simplifying wiring and installation space.

Precise Hazard Area Monitoring: The 34 mm short probe design is ideal for thin-walled fluid diaphragm bearing locations, and is BR-certified for predictive maintenance in compliant markets such as Brazil, including petrochemical plants, offshore drilling platforms, and large power plants.

Materials and Advantages

Housing and Probe Tip Material: Made of PPS high-grade engineering plastic. This material incorporates conductive fibers to eliminate static electricity generated by friction and is absolutely chemically inert to almost all known industrial solvents, strong acids, and strong alkalis.

Oil Resistance and Airtightness: The probe head and housing sleeve seals utilize Viton O-rings. This configuration allows for prolonged immersion in various synthetic turbine oils, fire-resistant oils, and extreme pressure lubricants, maintaining IP66 airtightness even in bearing housing environments reaching up to 100°C, preventing oil vapors from seeping into the internal circuitry through the outer casing.
