Bently Nevada 31000-16-05-30-050-02-02 Probe Housing

31000 Proximity Probe Housing by Bently Nevada

Product Introduction

The Bently Nevada 31000-16-05-30-050-02-02 is a robust proximity probe housing built for demanding machinery monitoring applications. This housing accommodates a 3300 XL 8 mm probe with a connector option. Its construction uses advanced materials to ensure long-term reliability. The housing is specifically configured with a 0.5 m probe cable, a 3.0 in standoff adapter, and 5 in probe penetration. Furthermore, it includes two 3/4-14 NPT fittings and one plug for flexible installation. This model also features a 3/4-14 NPT mounting thread, which is required when ordering the standoff adapter option.

Technical Specifications

The Bently Nevada 31000-16-05-30-050-02-02 boasts impressive technical parameters. Its protection ratings are a key highlight. Specifically, the housing carries a Type 4X rating certified by the Canadian Standards Association (CSA). Additionally, it holds an IP66 rating verified by SC115582-1 (e) 106. The unit also meets CENELEC standard EN50014 for electrostatic dissipation of plastic materials in hazardous areas.

The housing material is a glass-reinforced Polyphenylene Sulfide (PPS) thermoplastic containing conductive fibers. This material provides excellent strength and chemical resistance. The sleeve and retaining chain are made from AISI 304 stainless steel. Meanwhile, the outer sleeve and exterior screws use AISI 303 stainless steel. For sealing, the O-ring material is Neoprene®.

The housing demonstrates significant impact strength. BASEEFA certified it to withstand two separate 4 Joule (3.0 ft·lb) impacts at both -39°C and 115°C. Moreover, CSA verified samples of the housing and cover to withstand a 7 Joule (5.2 ft·lb) impact at ambient temperature. The temperature rating for the entire assembly spans from -51°C to +105°C (-60°F to +221°F).

Mechanical and Environmental Parameters

This model weighs 1.2 kg typically. The recommended torque for the retaining nut is 29.4 N·m (260 in·lb). This ensures a secure and vibration-resistant installation.

The housing also exhibits substantial mechanical strength. Testing showed the outer sleeve mounted horizontally on a test stand. The housing itself was mounted on the outer sleeve through an end hole. It successfully supported a 912 N (205 lb) load. This load was placed approximately 38 mm (1.5 inches) from the unsupported end. The cover was fastened, and the grounding liner was installed during this test.

Therefore, the 31000-16-05-30-050-02-02 is suitable for harsh environments. It effectively protects the probe from physical damage and environmental ingress. Its rugged stainless steel components resist corrosion, and the PPS housing provides excellent dimensional stability.

Installation Guidelines

Installing the Bently Nevada 31000 housing requires careful attention. First, ensure the mounting surface is clean and flat. Next, apply the recommended torque of 29.4 N·m to the retaining nut. This secures the assembly without overstressing components.

When installing the 3300 XL probe, confirm the probe penetration option of 5 inches is suitable for your application. The 0.5 m cable length provides flexibility for connections. Additionally, use the provided 3/4-14 NPT fittings and plug to seal conduit entries correctly. Remember, the mounting thread option is 3/4-14 NPT, which is mandatory with the standoff adapter. Proper installation of the included grounding liner is also critical for safety and signal integrity.

The housing's Type 4X and IP66 ratings depend on correctly installed and tightened covers and fittings. Therefore, inspect all seals and O-rings during installation. Replace any damaged parts to maintain the specified protection level.
