31000-16-05-00-036-03-00 | Bently Nevada 8mm Probe Housing

Introduction to the 31000-16-05-00-036-03-00

When you need reliable vibration monitoring in demanding industrial environments, the 31000-16-05-00-036-03-00 from Bently Nevada offers a robust solution. This 31000 series proximity probe housing is engineered to protect your 3300 XL 8 mm probe while maintaining signal integrity. With a 0.5 m (20 in) cable length, it suits applications where space is tight and precision is critical.

This housing is built to withstand harsh conditions, featuring a glass-reinforced Polyphenylene Sulfide (PPS) thermoplastic with conductive fibers. Its stainless steel components ensure long-term durability. As a result, you get a housing that performs consistently, even in challenging settings.

Key Features and Technical Specifications

The 31000-16-05-00-036-03-00 is designed with specific options to match your installation needs. Here are the core specifications:

• Probe Option: 3300 XL 8 mm probe with connector
• Cable Length: 0.5 m (20 in)
• Standoff Adapter: None
• Probe Penetration: 3.6 in
• Fittings: Two plugs, one 3/4-14 NPT fitting, one 3/4-14 to 1/2-14 NPT SST reducer, and cable seal grip for various cable sizes
• Mounting Thread: No outer sleeve, retainer, or retaining nut
• Housing Material: Glass-reinforced PPS thermoplastic with conductive fibers
• Sleeve Material: AISI 304 stainless steel
• 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)

One distinctive feature is the housing's impact strength. It is certified by BASEEFA to withstand two separate 4 Joule (3.0 ft·lb) impacts at -39°C and at 115°C. This means the housing can endure physical shocks without compromising the probe inside, which is essential in high-vibration environments.

Applications and Use Cases

The 31000-16-05-00-036-03-00 is ideal for rotating machinery monitoring, such as turbines, compressors, and pumps. Its robust construction makes it suitable for outdoor installations, especially where moisture or dust could be an issue. For example, in a petrochemical plant, this housing protects the proximity probe from harsh weather, ensuring accurate vibration readings.

Additionally, the housing's Type 4X and IP66 ratings mean it can handle hose-directed water, so it is a good choice for washdown areas. The CENELEC EN50014 rating for electrostatic dissipation also makes it safe for use in hazardous areas with plastic materials.

Installation and Setup

When installing the 31000-16-05-00-036-03-00, follow the manufacturer's guidelines to ensure proper sealing. The housing is designed to seal differential pressure between the probe tip and the housing main body when used with a 3300 XL 8 mm probe. Therefore, ensure the O-rings are correctly seated to maintain the seal.

For the fittings, use the provided 3/4-14 NPT fitting and reducer as needed. The cable seal grip accommodates cable sizes from 1/8 to 3/8 inches, so choose the appropriate grommet for your cable. Also, note that the mounting thread option is none, so you may need to provide your own mounting method.

Maintenance and Reliability

Regular inspection of the housing is recommended to ensure the O-rings remain intact and the housing is free from cracks. Since the housing is made of plastic, avoid exposing it to excessive force beyond its impact rating. The stainless steel components resist corrosion, but it is still wise to check for any buildup of contaminants.

Because the housing is not designed to resist internal or external pressure, do not use it in pressurized applications unless you have consulted with the manufacturer. If you need pressure testing, contact the custom design department for assistance.

Compatibility and Integration

The 31000-16-05-00-036-03-00 is specifically designed for use with the Bently Nevada 3300 XL 8 mm probe. This ensures seamless integration with Bently Nevada monitoring systems. The housing's design allows for easy connection to your existing vibration monitoring setup.

For integration, verify that your system supports the 8 mm probe format. The housing does not include a standoff adapter, so you may need to order one separately if your application requires it.

Troubleshooting Common Issues

If you experience signal loss, check the cable connections and ensure the probe is properly seated. The housing's seal is critical; if water ingress occurs, inspect the O-rings for damage. Also, verify that the cable seal grip is tightened correctly to prevent moisture from entering.

In case of physical damage, replace the housing immediately to protect the probe. The impact strength is high, but repeated impacts can cause fatigue over time.
