Where It Excels in Industrial Use

• Integrated Rotating Machinery Protection
The Bently Nevada 330881-28-04-180-06-02 PROXPAC XL Proximity Transducer Assembly is designed for continuous shaft vibration and displacement monitoring on critical rotating equipment. Combining a 3300 XL 8 mm proximity probe with integrated Proximitor electronics, it provides a complete measurement solution without requiring a separate external Proximitor housing.

• Large Equipment Monitoring Applications
This PROXPAC XL configuration is suitable for turbines, compressors, generators, pumps, and other high-value machinery where accurate shaft position and vibration measurements are essential for condition monitoring and predictive maintenance programs.

• Simplified Field Installation
The integrated housing design reduces wiring complexity by combining the probe system and Proximitor sensor in one assembly. This helps improve installation efficiency while maintaining the measurement reliability expected from Bently Nevada proximity monitoring technology.

• Harsh Industrial Environment Operation
With a reinforced PPS housing, IP66 / Type 4X environmental protection, and industrial-grade construction, this assembly is designed for demanding applications in power generation, oil & gas, petrochemical, and process industries.

Key Strengths at a Glance

• 3300 XL 8 mm Proximity Technology
Uses proven eddy-current sensing technology to provide accurate non-contact measurement of shaft vibration, radial displacement, and position changes.

• Integrated Proximitor Sensor Design
The PROXPAC XL assembly incorporates its own 3300 XL Proximitor sensor, eliminating the requirement for a separate Proximitor enclosure and external extension cable.

• 40 mm Standoff Adapter Configuration
The 04 option specifies a 40 mm standoff adapter, providing additional installation flexibility for machinery mounting arrangements requiring extended probe positioning.

• 180 mm Probe Penetration Length
The 180 option defines the probe penetration configuration, allowing the assembly to be installed on equipment requiring deeper access to the measurement location.
