Bently Nevada 330881-16-00-175-00-02 Integrated Proximity Transducer

Description

The 330881-16-00-175-00-02 is a PROXPAC XL Proximity Transducer assembly featuring a 3300 XL 8 mm proximity probe and an integrated Proximitor sensor. This self-contained unit combines the probe and signal conditioning electronics into a single housing, eliminating the need for separate extension cables or remote Proximitor enclosures. By simplifying the installation and reducing cable requirements, this assembly serves as a robust solution for continuous shaft vibration and axial position monitoring in industrial rotating machinery.

This specific configuration, identified by Option 16 (3300 XL 8 mm probe, non-approved), Option 00 (Standoff Adapter), Option 175 (175 mm probe penetration), and Option 00 (No outer sleeve/fittings), is designed for applications where direct mounting is preferred. The housing is constructed from advanced polyphenylene sulfide (PPS) with glass and conductive fibers, providing durability and electrostatic discharge protection in demanding field conditions.

Features

• Integrated design: Combines 3300 XL 8 mm probe and Proximitor sensor in one housing
• Reduces installation complexity by eliminating external extension cabling
• Constructed from PPS (polyphenylene sulfide) with conductive fibers for static dissipation
• Environmental rating: IP66 and Type 4X for severe environments
• Option 16: 3300 XL 8 mm proximity probe
• Option 175: 175 mm probe penetration depth

Applications

• Centrifugal pumps and compressors
• Industrial motors and gearboxes
• Hydroelectric and steam turbines
• Remote or space-constrained machinery protection
• Fluid film bearing monitoring

Installation Guidelines

The PROXPAC XL assembly should be mounted to the machine case using the specified 3/4-14 NPT thread. Ensure the probe tip is correctly gapped at the recommended 1.27 mm (50 mils) from the target material. Field wiring connects directly to the internal Proximitor terminals; use 3-conductor shielded triax cable for signal integrity. Ensure the housing lid is properly sealed to maintain IP66/Type 4X protection ratings.
