Bently Nevada 330881-28-05-114-03-02 PROXPAC XL Proximity Transducer

Description

The 330881-28-05-114-03-02 PROXPAC XL Proximity Transducer assembly integrates a 3300 XL 8 mm proximity probe and a 3300 XL Proximitor sensor into a single, self-contained housing. This unit is designed for applications where simplifying installation and reducing wiring complexity are critical, eliminating the need for separate extension cables or remote Proximitor sensor housings. This configuration features Option 28, which provides a 3300 XL 8 mm probe with multiple hazardous area approvals.

The PROXPAC XL housing is constructed from polyphenylene sulfide (PPS), an advanced, molded thermoplastic reinforced with glass and conductive fibers for mechanical strength and electrostatic charge dissipation. This unit provides IP66 and Type 4X environmental protection, making it suitable for demanding industrial conditions. Field wiring connects directly to the assembly, streamlining the monitoring chain for shaft vibration and axial position measurement on critical rotating machinery.

Features

• Integrated Design: Combines 3300 XL 8 mm probe and Proximitor sensor in one enclosure to minimize external cabling.
• Option 28: 3300 XL 8 mm probe assembly with multiple agency approvals (CSA, ATEX, IECEx).
• Mechanical Construction: PPS thermoplastic housing for durability and charge dissipation.
• Mounting: Includes 3/4-14 NPT mounting thread (Option E=02) for secure installation.
• Fittings: Equipped with one M20 fitting and two plugs (Option D=03) for conduit termination.
• Environmental Rating: Designed for IP66 and Type 4X, providing protection against severe environments.

Applications

• Power generation and turbine machinery monitoring
• Oil and gas petrochemical processing
• Water treatment and industrial pump protection
• Severe environmental installations where reduced cabling is required

Installation Guidelines

The PROXPAC XL housing should be mounted according to standard Bently Nevada 3300 XL series practices, ensuring the probe tip is correctly gapped relative to the target material. The M20 fitting (Option 03) is provided for termination of rigid or flexible conduit. Ensure that conduit and field wiring are properly sealed to maintain the IP66/Type 4X rating. For hazardous area installations, adhere to local regulatory requirements and the specific control drawings referenced in the device documentation.
