Bently Nevada 330881-28-00-050-03-02 PROXPAC XL Proximity Transducer

Description

330881-28-00-050-03-02 specifies this PROXPAC XL Proximity Transducer metric configuration, featuring a 3300 XL 8 mm probe with multiple approvals (Option 28), 0 mm standoff length (Option 00), 50 mm probe penetration length (Option 050), M20 fitting kit with two plugs (Option 03), and a 3/4-14 NPT mounting thread (Option 02).

Unlike other options in this product family (such as Option 00/01 which do not include a probe or Option 16 which includes an unapproved probe), this assembly incorporates a fully approved 3300 XL 8 mm probe. This provides a self-contained transducer system with multiple hazardous area approvals, eliminating the need for separate probe cables and Proximitor housings. It is specifically configured for metric penetration requirements with no standoff adapter, allowing direct mounting into machine casings.

Features

• Option 28 probe package provides a 3300 XL 8 mm probe equipped with Multiple Approvals (CSA, ATEX, IECEx) for hazardous areas.
• Option 00 specifies no standoff adapter, keeping the assembly directly mounted to the casing interface.
• Option 050 provides a 50 mm probe penetration depth, optimized for metric dimensions.
• Option 03 kit includes one M20 fitting and two plugs, allowing secure conduit connection and sealing.
• Option 02 mounting thread specifies a 3/4-14 NPT thread, required for secure casing engagement.
• Integrated Proximitor sensor inside the housing lid eliminates the need for an extension cable.
• Glass-reinforced polyphenylene sulfide (PPS) thermoplastic housing is rated for Type 4X and IP66 severe environments.
• Conductive fibers inside the PPS housing effectively dissipate electrostatic charges.

Applications

The PROXPAC XL assembly is suited for rotating machinery protection, including:

• Shaft vibration and axial position measurements on high-speed rotating machinery.
• Severe environment operations requiring Type 4X and IP66 chemical-resistant protection.
• Hazardous area industrial applications requiring CSA, ATEX, and IECEx intrinsically safe certifications.
• Machinery installations where space constraints prevent the use of separate extension cables or remote Proximitor housings.

Installation Guidelines

Ensure standard industrial vibration engineering practices are followed during installation:

• Verify that the 50 mm sleeve penetration matches the machine casing port depth and target clearance requirements before mounting.
• Secure the 3/4-14 NPT thread with appropriate sealant or gasket to maintain the pressure seal of the machine housing.
• Route field wiring through the M20 conduit fitting (Option 03) to prevent moisture from traveling down the conduit into the enclosure.
• Avoid routing transducer cables adjacent to high-voltage lines to minimize electromagnetic interference.

Compliance and Certifications

The components of this assembly are certified as follows:

• CE Mark: Complies with applicable European standards.
• Hazardous Area Approvals (Option 28): Certified for intrinsically safe and non-incendive installations under CSA, ATEX, and IECEx schemes (including Class I, Zone 0, Ex ia IIC T4/T5 Ga, and Class I, Div 2, Groups A, B, C, D).
• Enclosure Protection: IP66 verified by BASEEFA; housing and lid material rated for Type 4X.
