Bently Nevada 31000-28-05-00-109-01-02 Probe Housing

Bently Nevada 31000-28-05-00-109-01-02 Proximity Probe Housing

Product Introduction

The Bently Nevada 31000-28-05-00-109-01-02 offers a durable mounting solution for the 3300 XL 8 mm proximity probe system. This housing ensures proper probe alignment and protection in demanding industrial settings. Furthermore, its design meets rigorous certification standards for both safety and environmental resistance. Specifically, this model supports a 10.9-inch probe penetration and includes a 0.5-metre cable with a connector. Additionally, the housing comes with one 3/4-14 NPT fitting and two plugs for versatile installation. Therefore, it serves as a critical component for vibration and position monitoring in turbines, compressors, and pumps.

Technical Specifications

The Bently Nevada 31000-28-05-00-109-01-02 works exclusively with the 3300 XL 8 mm probe, which carries multiple international approvals. Its cable length measures 0.5 metres (20 inches), providing adequate reach for many mounting configurations. Meanwhile, the probe penetration depth is fixed at 10.9 inches, ensuring consistent measurement gap settings. The housing does not include a standoff adapter, as indicated by the "00" option code. For mounting, it uses a 3/4-14 NPT thread, which is mandatory when a standoff adapter is required. The fittings package includes one 3/4-14 NPT fitting and two plugs, giving you flexibility for conduit connections.

This housing model carries a Type 4X rating, certified by the Canadian Standards Association (CSA). Moreover, it holds an IP66 rating, verified under SC115582-1 (e) 106, ensuring complete protection against dust and high-pressure water jets. The CENELEC standard EN50014 rating also qualifies it for electrostatic dissipation in hazardous areas. Consequently, this housing suits both indoor and outdoor installations where moisture, dust, or explosive atmospheres may exist.

Housing Material and Construction

The main housing uses glass-reinforced Polyphenylene Sulfide (PPS) thermoplastic with conductive fibers embedded. This material delivers exceptional dimensional stability and chemical resistance across a wide temperature range. The sleeve and retaining chain are fabricated from AISI 304 stainless steel, offering excellent corrosion resistance. Meanwhile, the outer sleeve and all exterior screws use AISI 303 stainless steel, which provides superior machinability and surface finish. The O-ring seals are made from Neoprene, ensuring a tight seal against moisture and contaminants.

Mechanical and Environmental Ratings

This housing demonstrates outstanding mechanical strength for industrial applications. The outer sleeve supports up to 912 N (205 lb) when mounted horizontally, with the load applied 38 mm from the unsupported end. This capacity ensures stable probe positioning even under moderate mechanical stress. Regarding impact resistance, BASEEFA certified this housing to withstand two separate 4 Joule impacts at both -39°C and 115°C. Additionally, CSA verified that samples withstand a 7 Joule impact at ambient room temperature. These ratings guarantee reliable operation despite accidental impacts or mechanical shocks.

The operating temperature range spans from -51°C to +105°C (-60°F to +221°F). This broad tolerance enables deployment in freezing outdoor environments or near high-temperature machinery. The recommended torque for the retaining nut is 29.4 N·m (260 in·lb), ensuring secure assembly without damaging components. The typical weight of this housing is 1.2 kg (2.6 lb), which simplifies handling and installation.

Installation Guidelines

Installing the Bently Nevada 31000-28-05-00-109-01-02 requires attention to several key factors. First, ensure the mounting surface is clean and free from debris before attaching the housing. Next, thread the 3/4-14 NPT fitting securely into the mounting hole, applying appropriate sealant if required. Then, insert the 3300 XL 8 mm probe through the housing, adjusting the penetration depth to 10.9 inches as specified. Tighten the retaining nut to the recommended torque of 29.4 N·m using a calibrated torque wrench.

For optimal performance, route the 0.5-metre probe cable carefully to avoid sharp bends or excessive tension. Additionally, verify that the O-ring is properly seated before closing the cover. If you plan to use conduit connections, attach the two plugs to the unused ports to maintain the IP66 seal. Finally, perform a continuity check on the grounding liner to ensure proper electrostatic dissipation in hazardous areas.

Frequently Asked Questions

1. Does this housing work with other probe models besides the 3300 XL 8 mm?
No, the Bently Nevada 31000-28-05-00-109-01-02 is specifically designed for the 3300 XL 8 mm probe. Using other probe types may compromise the fit, sealing, or measurement accuracy.

2. Can I use this housing in outdoor installations with direct rain exposure?
Yes, the IP66 and Type 4X ratings make this housing suitable for outdoor use. It resists high-pressure water jets and corrosive environments effectively.

3. What should I do if the cable length of 0.5 metres is insufficient for my setup?
This model comes with a fixed 0.5-metre cable. For longer cable requirements, please consider other variants in the 31000 series with different cable length options.

4. Is the 3/4-14 NPT thread compatible with standard conduit fittings?
Yes, the 3/4-14 NPT thread is a common industrial standard. It works with most conduit fittings and adapters used in North American and international installations.

5. How do I maintain the IP66 seal after opening the housing for inspection?
Inspect the O-ring for damage each time you open the cover. Replace it if you notice cuts, compression set, or deformation. Clean the sealing surfaces and tighten the cover evenly to restore the full IP66 protection.
