Bently Nevada 31000-16-10-00-122-00-05 | 3300 XL Assembly

Product Overview

The 31000-16-10-00-122-00-05 is a high-performance Proximity Probe Housing from the Bently Nevada 31000 series, specifically configured for the 3300 XL 8 mm probe system. This model provides superior environmental shielding for vibration sensors in hazardous and high-impact zones. Featuring a substantial 12.2-inch (310 mm) penetration depth and a 7/8-14 UNF mounting thread, it ensures precise sensor positioning within the machine casing. The housing is constructed from glass-reinforced PPS thermoplastic with conductive fibers, providing an optimal balance of thermal stability and electrostatic safety. With a robust weight of approximately 1.1 kg, this assembly is engineered to withstand extreme mechanical loads and corrosive atmospheres.

Technical Specifications

Engineering Advantages

• Advanced Material Science: The PPS thermoplastic housing features UL94 V-0 flame rating and conductive fibers to prevent electrostatic buildup in hazardous areas.
• Extreme Impact Resistance: Certified to withstand 7J (5.2 ft·lb) impacts at room temperature, protecting delicate internal sensors from mechanical debris.
• Superior Sealing Technology: Utilizes Neoprene® O-rings with minimal oil swelling (<10%), maintaining an airtight seal even in hydrocarbon-rich environments.
• High Load Capacity: Supports lateral loads up to 912N (205 lb), ensuring structural integrity in high-vibration machinery like large turbines and compressors.

Installation & Maintenance

Installation of the Bently Nevada 31000-16-10-00-122-00-05 requires careful attention to the 29.4 N·m (260 in·lb) torque specification for the mounting nut to ensure a vibration-proof seal. The 12.2-inch sleeve should be inspected for clearance before final insertion. With its net weight of 1.1 kg and 304 stainless steel hardware, it offers 500 hours of salt spray resistance (ASTM B117), making it suitable for offshore and coastal applications. Periodic checks of the Neoprene® O-ring are recommended during planned outages to ensure continued IP66 performance.
