The 31000-26-05-00-100-03-02 includes a fittings option with two plugs, one 3/4-14 NPT fitting, a reducer, and a cable seal grip with grommets for various cable sizes. This ensures a secure and adaptable installation. The housing is designed to seal differential pressure between the probe tip and the main body when used with a 3300 XL 8 mm probe.

Durability and Protection Ratings

Engineered for harsh environments, the 31000-26-05-00-100-03-02 boasts a Type 4X rating certified by CSA and an IP66 rating verified by SC115582-1 (e) 106. This means it is protected against dust ingress and powerful water jets. Additionally, it meets CENELEC standard EN50014 for electrostatic dissipation of plastic materials in hazardous areas.

The housing impact strength is certified by BASEEFA to withstand two separate 4 Joule impacts at -39°C and 115°C. Furthermore, samples verified by CSA can withstand a 7 Joule impact at ambient temperature. This ruggedness helps ensure reliable operation even under physical stress.

Applications and Use Cases

The 31000-26-05-00-100-03-02 is ideal for machinery protection and condition monitoring in industries such as oil and gas, power generation, and manufacturing. It is specifically designed for use with 3300 XL NSv probes, making it suitable for measuring shaft vibration and position in turbines, compressors, pumps, and motors.

For example, in a petrochemical plant, this housing can protect a vibration probe on a critical pump, enabling early detection of bearing wear or misalignment. This proactive approach helps minimize unplanned downtime and maintenance costs. The housing's robust construction ensures it can withstand the rigors of continuous industrial operation.

Installation and Setup

Proper installation is essential for optimal performance. The 31000-26-05-00-100-03-02 features a 3/4-14 NPT mounting thread, which is required when ordering a standoff adapter. The recommended torque for the retaining nut is 29.4 N·m (260 in·lb).

When installing, ensure the probe cable is routed correctly through the cable seal grip and that all fittings are tightened securely. The housing is designed to seal against hose-directed water per NEMA 4X and IP66 standards, but it is not designed to resist internal or external pressure. Probes are not pressure tested prior to shipment; contact the custom design department if pressure seal testing is required.

Maintenance and Reliability

To ensure long-term reliability, periodic inspection of the housing and its components is recommended. Check the O-rings and seals for any signs of wear or damage, and verify that all fittings remain tight. The stainless steel components offer excellent corrosion resistance, but regular cleaning can help maintain their appearance and function.

Given the robust construction and high-quality materials, the 31000-26-05-00-100-03-02 is designed for extended service life. By following a routine maintenance schedule, you can maximize the lifespan of the housing and ensure consistent monitoring performance.

Compatibility and Integration

The 31000-26-05-00-100-03-02 is specifically designed for use with 3300 XL NSv probes. It is part of the Bently Nevada 31000 series, ensuring seamless integration with existing monitoring systems. The housing's design allows for easy mounting and positioning of the probe, making it a versatile choice for various machinery configurations.
