31000-28-10-00-235-00-02 | Bently Nevada 8mm Probe Housing

Introduction to the 31000-28-10-00-235-00-02

When your rotating machinery demands precise vibration monitoring, the 31000-28-10-00-235-00-02 from Bently Nevada delivers a robust housing solution. This 31000 Proximity Probe Housing is engineered to seal differential pressure between the probe tip and the housing main body when paired with a 3300 XL 8 mm probe. As a result, it ensures stable, accurate readings even in challenging industrial settings.

Manufactured in the U.S.A., this housing combines durable materials with a thoughtful design. Its glass-reinforced Polyphenylene Sulfide (PPS) thermoplastic body contains conductive fibers, providing both strength and electrostatic dissipation. Consequently, the housing meets stringent protection standards, including Type 4X and IP66 ratings, making it suitable for washdown and outdoor applications.

Key Features and Technical Specifications

The 31000-28-10-00-235-00-02 stands out with several features that support reliable operation:

• Probe Compatibility: Designed for the 3300 XL 8 mm probe, ensuring a precise fit.
• Probe Cable Length: 1.0 in, allowing for flexible installation.
• Probe Penetration: 23.5 in, accommodating deep mounting requirements.
• Mounting Thread: 3/4-14 NPT, providing a secure and standard connection.
• Housing Material: Glass-reinforced PPS thermoplastic with conductive fibers for durability and static control.
• Sleeve Material: AISI 304 stainless steel for corrosion resistance.
• Outer Sleeve and Screws: AISI 303 stainless steel for added strength.
• O-Ring Material: Neoprene® for effective sealing.
• Temperature Rating: -51°C to +105°C (-60°F to +221°F), suitable for extreme environments.
• Weight: 1.2 kg (2.6 lb) typical, balancing sturdiness with ease of handling.

Notably, the housing impact strength is certified by BASEEFA to withstand two separate 4 Joule (3.0 ft·lb) impacts at -39°C and 115°C. Additionally, CSA verified samples withstand a 7 Joule (5.2 ft·lb) impact at ambient temperature. This resilience minimizes downtime from accidental damage.

Applications and Use Cases

The 31000-28-10-00-235-00-02 is ideal for industries where rotating equipment reliability is critical. For instance, in petrochemical plants, it monitors pumps and compressors, helping to detect early signs of bearing wear. Similarly, in power generation, it tracks turbine vibrations, enabling predictive maintenance that prevents costly failures.

Moreover, the housing's IP66 rating allows installation in areas subject to hose-directed water, such as washdown zones in food processing. Its wide temperature range also supports outdoor installations in extreme climates. Therefore, this housing adapts to diverse operational demands, ensuring consistent performance.

Installation and Setup

Proper installation is key to maximizing the performance of the 31000-28-10-00-235-00-02. First, verify that the mounting thread (3/4-14 NPT) matches your application's requirements. Then, when attaching the housing, apply the recommended torque of 29.4 N·m (260 in·lb) for the retaining nut to ensure a secure fit without over-tightening.

Additionally, confirm the probe cable length (1.0 in) and penetration depth (23.5 in) align with your setup. Since the housing is not designed to resist internal or external pressure, avoid pressurizing the assembly. If you need pressure testing, contact Bently Nevada's custom design department for guidance.

Maintenance and Reliability

To sustain long-term reliability, inspect the housing periodically for signs of wear or damage. Pay attention to the Neoprene O-ring, which provides the seal between the sleeve and housing; replace it if it shows cracks or compression set. Also, check the stainless steel sleeves for corrosion, especially in harsh environments.

Furthermore, verify that the grounding liner is intact, as it aids in electrostatic dissipation. Regular inspections help prevent unexpected failures and extend the service life of your monitoring system. Consequently, you reduce maintenance costs and improve overall plant uptime.

Compatibility and Integration

The 31000-28-10-00-235-00-02 is specifically designed for use with the 3300 XL 8 mm probe. This compatibility ensures seamless integration with Bently Nevada's monitoring systems. While the data does not specify communication protocols, the housing works with the probe to transmit vibration signals to compatible monitors.

For a complete solution, pair this housing with Bently Nevada's 3300 XL series probes and related accessories. Always consult the official documentation to confirm compatibility with your existing monitoring equipment.
