31000-16-05-00-023-02-02 | Bently Nevada 3300 XL 8mm Probe Housing

Introduction to the Bently Nevada 31000-16-05-00-023-02-02

When machinery vibration threatens uptime, the 31000-16-05-00-023-02-02 from Bently Nevada provides a robust housing solution for 3300 XL 8 mm proximity probes. This 31000 series housing is engineered for harsh industrial environments, offering reliable protection for your monitoring system.

With a probe cable length of 0.5 m (20 in) and a probe penetration of 2.3 in, this model fits specific mounting requirements. The housing is made of glass-reinforced Polyphenylene Sulfide (PPS) thermoplastic with conductive fibers, ensuring durability and electrostatic dissipation.

Key Features and Technical Specifications

• Probe Option: 3300 XL 8 mm probe with connector
• Cable Length: 0.5 m (20 in)
• Standoff Adapter: None (00)
• Probe Penetration: 2.3 in (023)
• Fittings: Two 3/4-14 NPT fittings, one plug
• Mounting Thread: 3/4-14 NPT
• Temperature Rating: -51°C to +105°C (-60°F to +221°F)
• Weight: 1.2 kg (2.6 lb)

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.

Applications and Use Cases

This housing is ideal for rotating machinery monitoring in industries like power generation, oil and gas, and manufacturing. It is designed to seal differential pressure between the probe tip and housing body when used with a 3300 XL 8 mm probe, ensuring accurate vibration readings.

For example, in a steam turbine application, the housing protects the probe from environmental contaminants while maintaining signal integrity. Moreover, its Type 4X and IP66 ratings make it suitable for washdown areas or outdoor installations.

Installation and Setup

Proper installation is critical for optimal performance. The housing features two 3/4-14 NPT fittings and a mounting thread of 3/4-14 NPT. Ensure the probe cable is routed without sharp bends to avoid damage.

When mounting, use the recommended torque of 29.4 N·m (260 in·lb) for the retaining nut. Verify that the O-ring (Neoprene) is seated correctly to maintain the seal. The housing is not designed to resist internal or external pressure, so avoid pressurizing the assembly.

Maintenance and Reliability

Regular inspection of the housing and O-ring is recommended to ensure long-term reliability. The stainless steel components (AISI 304 and 303) resist corrosion, while the PPS housing withstands impacts and temperature extremes.

Periodically check the fittings and mounting thread for signs of wear or loosening. Although the housing is robust, environmental factors like chemical exposure can degrade the Neoprene O-ring over time. Replace worn parts promptly to maintain the seal integrity.

Compatibility and Integration

This housing is specifically designed for use with Bently Nevada 3300 XL 8 mm proximity probes. It integrates seamlessly with Bently Nevada monitoring systems, ensuring reliable data transmission.

For applications requiring a standoff adapter, note that this model (option 00) does not include one. If you need a standoff adapter, select the appropriate option when ordering.

Troubleshooting and Common Issues

One common issue is improper sealing, which can lead to moisture ingress. To avoid this, ensure the O-ring is clean and undamaged during installation. Another issue is incorrect mounting torque, which can cause leaks or damage. Always use a torque wrench set to 29.4 N·m.

If you experience signal loss, check the probe cable for cuts or kinks. The cable length is fixed at 0.5 m, so plan your routing accordingly. For pressure-related concerns, note that probes are not pressure tested before shipment; contact Bently Nevada's custom design department if you require pressure seal testing.
