Bently Nevada 330881-28-00-265-00-02 PROXPAC XL Proximity Transducer

Description

Option 28 (3300 XL 8 mm probe with Multiple Approvals) and Option 00 (no standoff adapter) specify this 330881 metric configuration — Bently Nevada 330881-28-00-265-00-02 PROXPAC XL Proximity Transducer.

This assembly features a metric-thread configuration (330881 series) with a 265 mm probe penetration option (Option 265). It includes two plugs and two washers with no external fittings (Option 00) and a 3/4-14 NPT mounting thread option (Option 02). By combining the probe and Proximitor sensor into a single, integrated assembly made of advanced molded Polyphenylene Sulfide (PPS), the PROXPAC XL eliminates the need for an extension cable and separate Proximitor housing.

Features

• Option 28: 3300 XL 8 mm proximity probe with Multiple Approvals package.
• Option 00: Direct mounting without a standoff adapter.
• Option 265: Explicit 265 mm metric probe penetration length.
• Option 00 (Fittings): Supplied with two plugs and two washers; no extra conduit fittings.
• Option 02 (Mounting Thread): Standard 3/4-14 NPT outer mounting thread.
• Polyphenylene Sulfide (PPS) housing material with glass and conductive fibers to dissipate electrostatic charges.
• Self-contained design: Built-in 3300 XL Proximitor sensor inside the cover removes the need for extension cables.
• Type 4X and IP66 environmental ingress protection rating.

Applications

• Machinery vibration and position monitoring in industrial rotating equipment.
• Direct installation on machine casings where a separate Proximitor sensor housing is not practical.
• Hazardous area applications requiring multiple global agency approvals (Option 28).
• Corrosive or severe industrial environments demanding a Type 4X and IP66 rated housing.

Installation Guidelines

• Grounding and Shielding: Connect the field wiring directly to the PROXPAC XL terminal strip inside the housing. Use twisted shielded 3-conductor cable (such as 18 AWG / 1.0 mm2 bulk field wire).
• Sleeve Support: If combined standoff adapter "B" and penetration "C" dimensions exceed 305 mm (12.0 in), provide additional sleeve support near the probe to stiffen the assembly and avoid resonant vibration.
• Tightening Torques: Tighten the housing retaining nut to 29.5 N-m (260 in-lb) and the probe sleeve locknut to 39.3 N-m (350 in-lb).
• Environmental Sealing: Ensure the Neoprene O-ring between the sleeve and the housing is properly seated. Prevent moisture from entering the housing via the conduit run.

Compliance and Certifications

• FCC Part 15 compliant (does not cause harmful interference).
• EMC Directive 2014/30/EU (EN 61000-6-2 and EN 61000-6-4 standards).
• RoHS Directive 2011/65/EU.
• Maritime certifications according to 2019 Rules for Conditions of Classification.
• Mechanical Housing: IP66 and Type 4X rating (verified by BASEEFA report T07/0709).
• Hazardous Area Approvals: Multiple Approvals package included (Option 28).
