31000-28-10-00-017-00-02 | Bently Nevada 1.2 kg Proximity Probe Housing

Introduction to the 31000-28-10-00-017-00-02

In the evolution of industrial machinery, the need for precise vibration monitoring has grown alongside the complexity of rotating equipment. The 31000-28-10-00-017-00-02 from Bently Nevada addresses this need with a robust housing designed to protect proximity probes in harsh conditions. This housing assembly is part of the 31000 series, engineered to seal differential pressure between the probe tip and the housing main body when used with a 3300 XL 8 mm probe.

Manufactured in the U.S.A., this model combines durable materials and thoughtful design to deliver reliable performance. With a temperature rating of -51°C to +105°C (-60°F to +221°F), it operates effectively across a wide range of environments. The housing weighs 1.2 kg, making it substantial yet manageable for installation.

Key Features and Technical Specifications

The 31000-28-10-00-017-00-02 offers several features that enhance its suitability for industrial applications. Each specification is carefully chosen to ensure durability and functionality.

• Probe Option: 3300 XL 8 mm probe with connector, multiple approvals.
• Probe Cable Length: 1.0 in.
• Standoff Adapter: None (option 00).
• Probe Penetration: 1.7 in.
• Fittings: None (option 00).
• Mounting Thread: 3/4-14 NPT (required if ordering standoff adapter).
• Housing Material: Glass-reinforced Polyphenylene Sulfide (PPS) thermoplastic with conductive fibers.
• Sleeve Material: AISI 304 stainless steel, retaining chain also AISI 304.
• 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) typical.

One distinctive aspect of this housing is its impact strength. Certified by BASEEFA to withstand two separate 4 Joule (3.0 ft·lb) impacts at -39°C and 115°C, and verified by CSA to withstand a 7 Joule (5.2 ft·lb) impact at ambient temperature, it offers exceptional resilience. This makes it suitable for environments where physical shocks are a concern.

Applications and Use Cases

The 31000-28-10-00-017-00-02 is designed for use in various industrial settings where vibration monitoring is critical. It is commonly employed in turbomachinery, pumps, compressors, and other rotating equipment to ensure operational health. The housing's ability to seal against hose-directed water, certified to NEMA 4X and IP66 standards, makes it ideal for outdoor or washdown areas. However, it is not designed to resist internal or external pressure, so it should not be used in pressurized applications.

For example, in a chemical processing plant, this housing can protect the probe from moisture and dust, ensuring accurate readings. Its wide temperature range also allows deployment in extreme climates, from arctic conditions to hot desert environments.

Installation and Setup

Proper installation is crucial for optimal performance. The mounting thread is 3/4-14 NPT, which is required if you order the standoff adapter. Ensure that the housing is securely fastened to avoid movement that could affect measurements. The recommended torque for the retaining nut is 29.4 N·m (260 in·lb).

When installing, verify that the probe cable length of 1.0 in is sufficient for your setup. The probe penetration of 1.7 in should be adjusted according to your machine's geometry. Always refer to the Bently Nevada installation manual for detailed guidance.

Maintenance and Reliability

Regular inspection is essential to maintain reliability. Check the O-rings periodically for wear, as they are critical for sealing. The housing's materials are chosen for corrosion resistance, but environmental factors can still cause degradation over time. It is recommended to follow the manufacturer's maintenance schedule and replace any worn components promptly.

The housing's robust construction, including stainless steel sleeves and impact-resistant plastic, contributes to a long service life. By investing in this housing, you reduce the risk of probe damage, which can lead to costly downtime.

Compatibility and Integration

The 31000-28-10-00-017-00-02 is specifically designed to work with the 3300 XL 8 mm probe. It is part of the 31000 series, ensuring seamless integration with Bently Nevada monitoring systems. For other compatibility details, consult the official documentation or contact Petro Auto Tech.

Troubleshooting and Common Issues

If you encounter measurement inaccuracies, first check the probe and cable connections. Ensure that the housing is properly sealed and that the O-rings are intact. If water ingress is suspected, verify the IP66 rating by inspecting the seals. For persistent issues, refer to the Bently Nevada troubleshooting guide.
