• Cable Length: 0.5 m (20 in) probe cable.
• Penetration: 6.3 in probe penetration.
• Mounting Thread: 3/4-14 NPT (required for standoff adapter).
• Housing Material: Glass-reinforced PPS thermoplastic with conductive fibers.
• Sleeve Material: AISI 304 stainless steel for sleeve and retaining chain.
• Outer Sleeve and Screws: AISI 303 stainless steel.
• O-Ring Material: Neoprene®.
• Temperature Rating: -51°C to +105°C (-60°F to +221°F).
• Weight: 1.2 kg (2.6 lb).

The housing is certified to Type 4X (CSA) and IP66, ensuring protection against water and dust ingress. Additionally, it meets CENELEC EN50014 for electrostatic dissipation in hazardous areas.

Applications and Use Cases

This housing is ideal for vibration monitoring on pumps, motors, and turbines. In petrochemical plants, the IP66 rating ensures reliable operation even with high-pressure washdowns. Similarly, in offshore platforms, the corrosion-resistant stainless steel components withstand salt spray. Furthermore, the wide temperature range makes it suitable for both arctic and desert environments.

Installation and Setup

When installing the 31000-16-05-00-063-03-02, ensure the mounting thread (3/4-14 NPT) is properly sealed. The fittings option includes two plugs, one 3/4-14 NPT fitting, a reducer, and a cable seal grip with grommets for cable sizes from 1/8 to 3/8 inches. Tighten the retaining nut to a recommended torque of 29.4 N·m (260 in·lb) for secure mounting.

Verify that the probe cable is routed without sharp bends to avoid damage. The housing can be oriented in any direction, but always follow the manufacturer's guidelines for optimal probe gap.

Maintenance and Reliability

Regular inspection of the housing and cable is recommended to ensure long-term reliability. Check the O-ring for signs of wear and replace if necessary. The stainless steel components resist corrosion, but periodic cleaning with a mild detergent is advised. The housing's impact strength, certified by BASEEFA, withstands 4 Joule impacts at extreme temperatures, reducing the risk of damage from accidental blows.

Compatibility and Integration

The 31000-16-05-00-063-03-02 is designed to work with Bently Nevada's 3300 XL 8 mm proximity probe systems. It integrates seamlessly with existing monitoring hardware, providing accurate vibration data. No additional adapters are needed unless a standoff adapter is required for specific installations.
