31000-16-10-15-030-03-02 | Bently Nevada 8mm Probe Housing

What Is the 31000-16-10-15-030-03-02?

When you need dependable protection for your 3300 XL 8 mm proximity probe, the 31000-16-10-15-030-03-02 from Bently Nevada delivers. This 31000 series housing safeguards the probe in demanding industrial environments. It is built to maintain accurate vibration measurements, which helps you detect machinery issues early.

This housing is designed for use with a 3300 XL 8 mm probe, as indicated by the probe option code 16. The housing assembly includes a standoff adapter (1.5 in) and a probe penetration of 3.0 in, ensuring proper positioning. The mounting thread is 3/4-14 NPT, which is required when using the standoff adapter.

Key Features and Technical Specs

The 31000-16-10-15-030-03-02 is engineered for reliability. Its construction materials are selected for durability and performance in harsh conditions.

• Housing material: Glass-reinforced Polyphenylene Sulfide (PPS) thermoplastic with conductive fibers.
• Sleeve material and retaining chain: AISI 304 stainless steel.
• Outer sleeve and exterior 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).
• Protection ratings: Type 4X (CSA certified), IP66 (verified), and CENELEC EN50014 for electrostatic dissipation.

One distinctive spec is the housing impact strength. It is certified by BASEEFA to withstand two separate 4 Joule impacts at -39°C and at 115°C. This means the housing can endure physical shocks without compromising the probe inside, which is critical in high-vibration environments.

Installation and Setup

Proper installation is key to accurate readings. The 31000-16-10-15-030-03-02 includes a fittings option with two plugs, one 3/4-14 NPT fitting, and a 3/4-14 to 1/2-14 NPT stainless steel reducer. A cable seal grip with grommets accommodates cable sizes from 1/8 to 3/8 inches.

When mounting, ensure the retaining nut is torqued to the recommended value of 29.4 N·m (260 in·lb). This helps maintain a secure seal and proper probe positioning. Also, verify that the mounting thread (3/4-14 NPT) matches your installation point.

Because the housing is not designed to resist internal or external pressure, avoid applying pressure to the assembly. The sealing is intended for hose-directed water protection per NEMA 4X and IP66, not for pressurized applications.

Maintenance and Reliability

Regular inspection of the 31000-16-10-15-030-03-02 housing is straightforward. Check the O-rings and seals periodically for wear or damage, as they are critical for maintaining the IP66 rating. The stainless steel components resist corrosion, but it is wise to clean them with a soft cloth if they become dirty.

Given the housing's impact strength, it can withstand accidental bumps, but you should still avoid dropping heavy objects on it. The temperature rating covers a wide range, so it suits most industrial settings. For long-term reliability, follow the manufacturer's manual for any specific maintenance intervals.

Applications and Use Cases

This housing is ideal for rotating machinery monitoring, such as turbines, compressors, and pumps. It is particularly useful in environments where water or dust might otherwise affect the probe. The Type 4X and IP66 ratings mean it can be installed outdoors or in washdown areas.

For example, in a paper mill, the housing protects the probe from moisture and physical impact, ensuring continuous vibration data. This helps maintenance teams identify bearing wear before it leads to unplanned downtime.

Compatibility and Integration

The 31000-16-10-15-030-03-02 is designed specifically for the Bently Nevada 3300 XL 8 mm probe. It is part of the 31000/32000 housing family, which is widely used with Bently Nevada monitoring systems. The housing's mounting options are standard NPT, making it compatible with common industrial mounting hardware.

For integration, you will need a compatible extension cable and monitor. The probe cable length option for this part is 1.0 m (39 in), which should be considered when routing to your monitoring equipment.

Common Questions
