Bently Nevada 31000-28-05-00-063-01-02 Probe Housing

31000 Proximity Probe Housing by Bently Nevada

Product Introduction

The Bently Nevada 31000-28-05-00-063-01-02 is a rugged proximity probe housing engineered for critical machinery monitoring applications. This housing specifically accommodates a 3300 XL 8 mm probe with multiple approvals, making it suitable for various industrial certifications. The configuration includes a 0.5 m probe cable and a 6.3 in probe penetration depth. Meanwhile, it comes with one 3/4-14 NPT fitting and two plugs for flexible conduit connections. This model ships without a standoff adapter, offering a more streamlined installation profile. The mounting thread is 3/4-14 NPT, which is required when a standoff adapter is specified.

Technical Specifications

The Bently Nevada 31000-28-05-00-063-01-02 delivers excellent technical performance for vibration and position monitoring. Its protection ratings are particularly noteworthy. Specifically, the housing holds a Type 4X rating certified by the Canadian Standards Association (CSA). In addition, it features an IP66 rating verified by SC115582-1 (e) 106. The unit also complies with CENELEC standard EN50014 for electrostatic dissipation of plastic materials in hazardous locations.

The housing construction uses a glass-reinforced Polyphenylene Sulfide (PPS) thermoplastic containing conductive fibers. This material offers outstanding strength and chemical resistance. The sleeve and retaining chain are manufactured from AISI 304 stainless steel. Furthermore, the outer sleeve and exterior screws utilize AISI 303 stainless steel for enhanced corrosion resistance. The O-ring material is Neoprene® for reliable sealing.

Impact strength is a critical feature of this housing. 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 spans from -51°C to +105°C (-60°F to +221°F), ensuring reliable operation in extreme environments.

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 specification ensures proper clamping force without damaging components.

The housing demonstrates substantial mechanical strength. Testing involved mounting the outer sleeve horizontally on a test stand. The housing attached to the outer sleeve through an end hole. It successfully supported a 912 N (205 lb) load placed approximately 38 mm (1.5 inches) from the unsupported end. The cover remained fastened, and the grounding liner was installed during testing.

Therefore, the 31000-28-05-00-063-01-02 is ideal for harsh environments. It effectively shields the probe from physical damage and environmental ingress. The stainless steel components resist corrosion effectively. The PPS housing maintains excellent dimensional stability across its temperature range.

Installation Guidelines

Installing the Bently Nevada 31000 housing requires following specific procedures. First, clean the mounting surface thoroughly before installation. Next, apply the recommended torque of 29.4 N·m to the retaining nut. This secures the assembly properly without over-tightening.

When installing the 3300 XL probe, confirm the 6.3 in probe penetration option matches your application requirements. The 0.5 m cable length provides adequate flexibility for most connection scenarios. Additionally, use the supplied 3/4-14 NPT fitting and two plugs to seal conduit entries effectively. Since this model has no standoff adapter, the mounting thread is not the primary concern, but the 3/4-14 NPT option remains available if needed. Proper installation of the included grounding liner is essential for safety and signal quality.

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 sealing components to maintain the specified protection level.
