Bently Nevada 330881-16-05-150-00-02 PROXPAC XL Proximity Transducer

Description

330881-16-05-150-00-02: Metric PROXPAC XL Proximity Transducer assembly featuring a 3300 XL 8 mm probe with no agency approvals (Option 16), a 50 mm standoff adapter (Option 05), and a 150 mm probe penetration length (Option 150). The enclosure is configured with standard dual-plug fittings and no conduit fittings (Option 00), secured via a 3/4-14 NPT mounting thread (Option 02).

This integrated system houses a 3300 XL Proximitor sensor directly within the polyphenylene sulfide (PPS) cover, eliminating the need for an external extension cable and separate Proximitor enclosure. This configuration simplifies wiring and installation by supporting direct field connections between the monitoring rack and the probe housing, while providing IP66 and Type 4X environmental protection in severe industrial environments. The metric design provides adjustable penetration depth through its integrated sleeve assembly, allowing external probe replacement or gap adjustments without requiring machine disassembly.

Features

• Integrated Design: Combines a 3300 XL 8 mm proximity probe and Proximitor sensor into a single self-contained housing, eliminating the field extension cable.
• PPS Thermoplastic Housing: Manufactured with glass and conductive fiber-reinforced polyphenylene sulfide (PPS) for superior resistance to chemicals and electrostatic dissipation.
• 50 mm Standoff Adapter: Includes an integrated standoff adapter to accommodate structural offsets or thermal expansion clearances.
• 150 mm Probe Penetration: Configured with a 150 mm metric probe sleeve for deep case-mounted vibration or position sensing.
• IP66 and Type 4X Protection: Housing provides ingress protection against dust, debris, and high-pressure hose-directed water.
• 3/4-14 NPT Mounting Thread: Standard industrial mounting connection for direct installation into machine cases.
• Standard Enclosure Fittings: Option 00 configuration includes two plastic plugs and two washers with no external conduit fittings.

Applications

• Hydroelectric, steam, and gas turbines
• Centrifugal and axial compressors
• Heavy-duty gearboxes and pumps
• Industrial rotating machinery requiring shaft vibration and axial position monitoring in harsh or chemical-heavy environments

Installation Guidelines

• Grounding and Shielding: Ensure proper grounding of the internal stainless steel grounding liner to the conduit or machine ground. Minimize noise by using tinned 3-conductor shielded field wiring.
• Moisture Prevention: Use sealant or thread compound on the mounting threads and unused conduit entries. Properly install the provided plugs and washers (Option 00) to maintain the IP66/Type 4X environmental seal.
• Probe Gapping: Set the initial probe gap to 1.27 mm (50 mils) corresponding to approximately -10.0 Vdc within the center of the linear calibration range.
• Sleeve Support: For assemblies where the combined standoff ("B") and penetration ("C") length exceeds 305 mm (12 in), provide additional structural sleeve support near the probe tip to prevent mechanical resonance.

Compliance and Certifications

• CE Mark (European Union compliance)
• IP66 / Type 4X Rating (BASEEFA verified)
