• Probe cable length: 0.5 m (20 in) cable option for flexible routing.
• Standoff adapter: 1.5 in standoff adapter ensures proper probe positioning.
• Probe penetration: 3.0 in penetration option for deep installation.
• Fittings: Two 3/4-14 NPT fittings and one plug for secure connections.
• Mounting thread: 3/4-14 NPT thread is required when using the standoff adapter.
• Housing material: Glass-reinforced Polyphenylene Sulfide (PPS) thermoplastic with conductive fibers.
• Temperature rating: Operates from -51°C to +105°C (-60°F to +221°F).
• Weight: 1.2 kg (2.6 lb) typical.

One standout specification is the IP66 rating, verified by SC115582-1 (e) 106, which ensures protection against hose-directed water. This makes the housing suitable for washdown environments where moisture is a constant threat.

Applications and Use Cases

This proximity probe housing is ideal for turbomachinery, pumps, compressors, and other rotating equipment where vibration monitoring is critical. In petrochemical plants, the IP66 and Type 4X ratings protect against water jets and corrosive atmospheres. Similarly, in power generation facilities, the housing’s rugged construction ensures reliable performance in high-temperature areas. Furthermore, its stainless steel components resist corrosion, extending service life in offshore and marine applications.

Installation and Setup Guide

Proper installation is key to accurate measurements. First, mount the housing using the 3/4-14 NPT thread, ensuring a secure fit. Next, connect the 0.5 m probe cable to the 3300 XL 8 mm probe, and adjust the standoff adapter to achieve the desired gap. Finally, tighten the retaining nut to the recommended torque of 29.4 N·m (260 in·lb) to prevent loosening. Always follow the manufacturer’s manual for detailed wiring and configuration steps.

Maintenance and Reliability

Regular inspection of the housing and O-rings is essential to maintain sealing integrity. The Neoprene O-ring between the sleeve and housing should be checked periodically for wear. Additionally, the stainless steel outer sleeve and screws resist corrosion, but they should be cleaned gently with a soft cloth if exposed to harsh chemicals. By following a routine maintenance schedule, you can extend the housing’s operational life and avoid unplanned downtime.

Compatibility and Integration

The 31000-28-05-15-030-02-02 is specifically designed for use with the 3300 XL 8 mm probe. It integrates seamlessly with Bently Nevada monitoring systems, providing accurate vibration data for analysis. The housing’s conductive PPS material also meets CENELEC EN50014 standards for electrostatic dissipation, making it safe for use in hazardous areas.
