Bently Nevada 31000-16-05-20-040-02-02 | Housing Assembly

Product Overview

The 31000-16-05-20-040-02-02 is a premium proximity probe housing system from Bently Nevada, designed to provide superior protection for 3300 XL 8 mm sensors. This system is constructed from a specialized glass-reinforced Polyphenylene Sulfide (PPS) composite, offering a surface resistivity of 10⁴ Ω·cm for effective electrostatic dissipation. Rated for high-pressure environments up to 35 bar (508 psi), it features a dual 3/4-14 NPT port configuration and robust AISI 304/303 stainless steel mechanical components. With a comprehensive certification suite including CSA Type 4X, ATEX, and IECEx, this housing is the industrial standard for machinery protection in explosive or corrosive atmospheres.

Technical Specifications

Engineering Advantages

• Advanced Sealing Technology: Utilizes Neoprene® O-rings rated for 15 MPa compression, ensuring hermetic integrity under fluctuating pressures.
• High Signal Integrity: The 0.5m cable features 3-layer shielding with 85% coverage to eliminate EMI/RFI interference in dense industrial electrical environments.
• Thermal Resilience: Maintains high linearity (0.12% shift per 10°C) across a wide operating range of -51°C to +105°C.
• Impact & Vibration Certified: Certified for 7J collision resistance and 15g RMS vibration tolerance, meeting EN 60079-0 standards for maximum durability.

Installation & Maintenance

For the 31000-16-05-20-040-02-02, professional installation is required to ensure the 4.0" penetration depth is accurately aligned with the target shaft. The dual 3/4-14 NPT ports allow for versatile conduit routing; ensure all unused ports are sealed with the provided NPT plugs to maintain the IP66 rating. Regular maintenance should include a visual inspection of the PPS housing for any chemical degradation and verification of the grounding path to ensure effective electrostatic dissipation.
