Bently Nevada 330881-28-06-155-00-02 PROXPAC XL Proximity Transducer

Product Summary

The Bently Nevada 330881-28-06-155-00-02 is a specialized Proximity Transducer Assembly that integrates an 8mm probe and a Proximitor sensor into a unified, heavy-duty housing. This all-in-one solution is engineered to measure vibration and position in rotating machinery while streamlining the installation process by eliminating external cable connections between the probe and sensor.

Technical Function and Industrial Application

The 330881-28-06-155-00-02 PROXPAC XL assembly serves as a primary sensing interface for Turbine Supervisory Instrumentation (TSI) systems. By merging the 8mm probe tip directly with the 3300 XL Proximitor electronics, this unit effectively tracks radial vibration, axial thrust, or speed measurements on critical rotating assets. Consequently, the integrated architecture removes the common failure points associated with intermediate coaxial cables and connectors, thereby increasing overall system reliability in high-vibration zones.

Engineers typically deploy this assembly on steam turbines, centrifugal compressors, and large industrial pumps where precision is paramount. Because the housing is built to withstand harsh chemical and thermal exposure, it performs consistently in refineries, power plants, and offshore facilities. Furthermore, the compact physical profile specifically addresses the challenges of modern machinery where mounting space is often restricted.
