The Bently Nevada 31000-28-05-00-059-02-02 offers a robust enclosure for proximity probe systems. Specifically, this housing accommodates the 3300 XL 8 mm probe with multiple agency approvals. Furthermore, its glass-reinforced PPS thermoplastic construction delivers exceptional durability in demanding settings. Therefore, this model suits power generation, oil and gas, and heavy manufacturing applications. Meanwhile, the housing maintains reliable performance across extreme temperatures. Its IP66 and Type 4X ratings ensure protection against dust, water, and corrosion. Additionally, the unit includes two 3/4-14 NPT fittings and one plug for flexible installation. The Bently Nevada 31000 series stands out for its impact resistance and long service life.
This housing supports the 3300 XL 8 mm probe with connector options. The probe cable length measures 0.5 metre (20 inches) for convenient routing. Specifically, option code 28 indicates the probe type with multiple certifications. The standoff adapter option is set to 00, meaning no adapter is included. Moreover, probe penetration is fixed at 5.9 inches (option 059), which suits most standard mounting depths. The fittings option provides two 3/4-14 NPT fittings plus one plug. Additionally, the mounting thread matches 3/4-14 NPT (option 02), which is required for proper installation. Therefore, this configuration covers typical machinery monitoring needs without extra adapters.
The housing carries a Type 4X rating certified by the Canadian Standards Association (CSA). In addition, it meets IP66 requirements, verified by test report SC115582-1 (e) 106. This combination guarantees total protection against dust ingress and powerful water jets. Furthermore, the housing complies with CENELEC standard EN50014 for electrostatic dissipation. Specifically, this rating applies to plastic materials located in hazardous areas. Consequently, the unit prevents dangerous static discharge in explosive atmospheres. The operating temperature range spans from -51°C to +105°C (-60°F to +221°F) . Therefore, this Bently Nevada 31000 housing performs reliably in freezing cold and extreme heat.
The housing body uses glass-reinforced Polyphenylene Sulfide (PPS) thermoplastic with conductive fibers. This material offers high mechanical strength and chemical resistance. Additionally, the sleeve and retaining chain are fabricated from AISI 304 stainless steel for excellent corrosion resistance. The outer sleeve and exterior screws use AISI 303 stainless steel, which provides good machinability and durability. Meanwhile, the O-ring is made of Neoprene , ensuring a reliable seal against moisture and contaminants. These carefully selected materials extend the product's operational life in harsh environments.
The housing demonstrates remarkable structural integrity. For instance, tests show the outer sleeve supports 912 N (205 lb) when mounted horizontally with the housing attached through an end hole. This load was applied 38 mm (1.5 inches) from the unsupported end with the cover fastened. Moreover, the impact strength is certified by BASEEFA to withstand two separate 4 Joule (3.0 ft·lb) impacts at both -39°C (-38°F) and 115°C (239°F). In addition, CSA verified that samples of the housing and cover survive a 7 Joule (5.2 ft·lb) impact at ambient room temperature. Therefore, this housing resists accidental blows and vibration without compromising probe alignment. The recommended torque for the retaining nut is 29.4 N·m (260 in·lb) .
First, ensure the mounting surface is clean and flat before installation. Next, thread the 3300 XL 8 mm probe through the housing using the 3/4-14 NPT mounting thread. Specifically, insert the probe to achieve the desired 5.9-inch penetration depth. Then, tighten the retaining nut to the recommended torque of 29.4 N·m (260 in·lb) . Additionally, connect the probe cable (0.5 metre length) to the system interface. The two 3/4-14 NPT fittings allow for conduit or cable gland connections. Meanwhile, use the supplied plug to seal any unused ports. Finally, verify that the grounding liner is properly installed to maintain electrostatic dissipation performance. For hazardous area installations, comply with local safety regulations regarding EN50014 requirements.
The operating temperature range is wide, from -51°C to +105°C. However, avoid sudden thermal shocks that could affect measurement accuracy. Furthermore, the IP66 and Type 4X ratings mean the housing withstands high-pressure washdowns and outdoor exposure. However, always ensure the cover is tightly fastened and the O-ring is in good condition before use. Periodic inspection of the retaining nut torque is recommended to maintain secure probe positioning.

1. Which probe does this housing support?
This housing is designed for the 3300 XL 8 mm probe with connector. The option code 28 confirms multiple agency approvals for that probe type.
2. What is the maximum ambient temperature for operation?
The Bently Nevada 31000 housing operates reliably between -51°C and +105°C (-60°F to +221°F).
3. Is this housing suitable for outdoor or washdown areas?
Yes. It carries IP66 and Type 4X ratings, so it resists dust, water jets, and corrosion. However, always keep the cover and O-ring properly sealed.
4. What torque should I apply to the retaining nut?
Apply 29.4 N·m (260 in·lb) to the retaining nut. This ensures the probe stays secure without damaging the housing.
5. Does this model include a standoff adapter?
No. The option code 00 means no standoff adapter is included. If you need one, please order the adapter separately.
