The Bently Nevada 330880-28-15-035-00-02 is a high-performance PROXPAC XL Proximity Transducer Assembly. This unit integrates a 3300 XL 8 mm proximity probe and a Proximitor sensor into a single, self-contained housing. By combining these components, the assembly eliminates the requirement for external extension cables and separate Proximitor housings, simplifying field wiring directly between the monitoring system and the transducer assembly.

Features

• Integrated 3300 XL 8 mm proximity probe and sensor system.
• Constructed from Polyphenylene Sulfide (PPS), an advanced molded thermoplastic reinforced with glass and conductive fibers for structural strength and electrostatic dissipation.
• Rated for Type 4X and IP66 environments, providing robust protection in severe industrial conditions.
• Eliminates the need for extension cables between the probe and sensor.
• Direct interface with monitoring equipment reduces installation complexity.

Applications

• Steam and Gas Turbines: Monitoring for shaft vibration, axial position, and eccentricity.
• Centrifugal Compressors: Precision tracking of shaft displacement during high-speed gas compression.
• Hydro Turbines: Rotational dynamics monitoring in power generation.
• Centrifugal Pumps: Early detection of bearing wear and misalignment through vibration analysis.
• Electric Motors and Generators: Ensuring bearing health and shaft alignment to prevent mechanical failure.

Technical Specifications

Installation Guidelines

• Mount the assembly using the specified 3/4-14 NPT mounting thread.
• Ensure all conduit entries are properly sealed to maintain the IP66/Type 4X rating and prevent moisture ingress.
• Verify that the 1.5-inch standoff and 3.5-inch probe penetration provide adequate clearance from all internal machine components before final installation.
• Handle the probe tip with care to avoid mechanical damage or calibration drift.
• Ensure the system is powered down before performing any wiring or maintenance on the transducer assembly.

FAQ

What is the primary advantage of the PROXPAC XL design?

The PROXPAC XL design integrates the Proximitor sensor directly into the housing, removing the need for extension cables and separate sensor mounting, which simplifies installation and reduces potential points of failure.

What materials are used in the housing?

The housing is manufactured from Polyphenylene Sulfide (PPS), a durable thermoplastic reinforced with glass and conductive fibers to provide strength and dissipate electrostatic charges.

Is this unit suitable for harsh environments?

Yes, the assembly is rated for IP66 and Type 4X, making it suitable for use in demanding industrial environments where protection against dust and moisture is required.
