Bently Nevada 330881-28-10-060-06-02 PROXPAC XL Proximity Transducer

Description

330881-28-10-060-06-02 specifies a metric PROXPAC XL proximity transducer assembly configured with an integrated 3300 XL 8 mm proximity probe featuring multiple hazardous area approvals (Option 28), a 100 mm standoff adapter (Option 10), and a 60 mm probe penetration length (Option 060).

Unlike standard unapproved options, this configuration integrates the proximity probe and the 3300 XL Proximitor sensor directly into a single molded thermoplastic housing made of glass-reinforced polyphenylene sulfide (PPS). This design eliminates the requirement for separate extension cables and external housings, simplifying field installation by routing connections directly from the monitor to the field device. The housing provides IP66 and Type 4X environmental protection against harsh, corrosive, and wet conditions.

Features

• Option 28 specifies an integrated 3300 XL 8 mm proximity probe with Multiple Approvals.
• Option 10 provides a 100 mm standoff adapter to accommodate specific structural clearance needs.
• Option 060 sets the probe penetration sleeve length to exactly 60 mm.
• Option 06 fittings configuration includes one 3/4-14 NPT fitting, one 3/4-14 NPT to 1-1/2-14 NPT stainless steel reducer, and two plugs.
• Option 02 designates a 3/4-14 NPT mounting thread.
• Integrated Proximitor sensor built directly inside the housing lid, removing the need for a separate junction box.
• Molded PPS thermoplastic housing contains conductive fibers to effectively dissipate electrostatic charges.

Applications

• Radial vibration and axial position measurements on rotating machinery.
• Corrosive industrial environments requiring Type 4X and IP66 certified protection.
• Field monitoring setups requiring a simplified installation footprint with fewer cable runs.

Installation Guidelines

• Maintain a recommended probe gap setting of 1.27 mm (50 mils) to establish the midpoint of the linear range.
• Ensure the sleeve and cover O-rings are clean and properly seated during housing assembly to preserve the IP66 and Type 4X rating.
• Apply a tightening torque of 29.5 N-m (260 in-lb) to the retaining nut and 39.3 N-m (350 in-lb) to the probe sleeve locknut.
• Ensure field wire shielding is correctly grounded in accordance with local safety and electrical standards.

Compliance and Certifications

• Compliant with European CE mark requirements.
• CSA/NRTL/C Approved for hazardous areas.
• ATEX and IECEx certification codes: Ex ia IIC T4/T5 Ga, Ex ec IIC T4/T5 Gc, Ex ia IIIC T90C/T105C Dc.
• Molded housing certified to Type 4X and IP66 ratings against hose-directed water and dusty environments.
