Bently Nevada 31000-16-05-30-050-02-02 | Explosion-Proof Probe Housing

Product Overview

The 31000-16-05-30-050-02-02 is a rugged, glass-reinforced Polyphenylene Sulfide (PPS) proximity probe housing manufactured by Bently Nevada. Engineered for extreme industrial environments, this housing provides a Type 4X and IP66 rated protective enclosure for 3300 XL 8mm proximity probes. The conductive fiber-reinforced PPS material ensures electrostatic dissipation, meeting CENELEC standards for hazardous area safety. Weighing approximately 1.2 kg, this assembly features stainless steel sleeves and neoprene O-rings, offering a highly resilient solution for mounting vibration sensors on large rotating machinery such as turbines and compressors.

Technical Specifications

Engineering Advantages

• Extreme Impact Resistance: Certified by BASEEFA to withstand 4 Joule impacts at extreme temperatures ranging from -39°C to 115°C.
• Advanced Material Science: The PPS housing contains conductive fibers for electrostatic dissipation, essential for CENELEC EN50014 hazardous area compliance.
• Environmentally Sealed: Utilizing Neoprene® O-rings and AISI 303/304 stainless steel components to prevent moisture ingress and corrosion.
• High Load Capacity: Robust structural design supports up to 912 N (205 lb) of force, ensuring stability under mechanical stress.

Installation & Maintenance

When installing the 31000-16-05-30-050-02-02, ensure the 3/4-14 NPT mounting threads are properly sealed with industrial-grade sealant to maintain the IP66 rating. The recommended torque for the retaining nut is 29.4 N·m (260 in·lb). Given the 5-inch penetration depth and 3-inch standoff, verify internal clearances within the machine case before final tightening. Regularly inspect the Neoprene O-rings for signs of degradation if the housing is exposed to harsh chemical vapors.

Technical FAQs

Q1: Does this housing include the 3300 XL probe?
