31000-28-05-00-028-01-02 | Bently Nevada 8 mm Proximity Probe Housing

Product Overview: Bently Nevada 31000-28-05-00-028-01-02

When you need dependable vibration monitoring in harsh industrial environments, the 31000-28-05-00-028-01-02 from Bently Nevada delivers the protection your sensors require. This 31000 series proximity probe housing is engineered to shield a 3300 XL 8 mm probe while maintaining signal integrity. With a robust design and multiple approvals, it is a trusted choice for rotating machinery protection.

The housing is made from glass-reinforced Polyphenylene Sulfide (PPS) thermoplastic containing conductive fibers. This material provides excellent mechanical strength and electrostatic dissipation, making it suitable for hazardous areas. The sleeve and retaining chain are AISI 304 stainless steel, while the outer sleeve and exterior screws use AISI 303 stainless steel for corrosion resistance.

Key Features & Technical Specifications

• Probe Option: 28 = 3300 XL 8 mm probe with multiple approvals.
• Cable Length: 05 = 0.5 metre (20 in) cable.
• Standoff Adapter: 00 = No standoff adapter.
• Probe Penetration: 028 = 2.8 inches.
• Fittings: One 3/4-14 NPT fitting and two plugs.
• Mounting Thread: 3/4-14 NPT (required if ordering standoff adapter).
• Temperature Rating: -51°C to +105°C (-60°F to +221°F).

One standout feature is the housing's impact strength. Certified by BASEEFA to withstand two separate 4 Joule impacts at -39°C and 115°C, and verified by CSA to handle a 7 Joule impact at room temperature. This ensures durability in extreme conditions.

Industry Applications and Use Cases

The 31000-28-05-00-028-01-02 is ideal for use in turbomachinery, compressors, pumps, and other rotating equipment where precise shaft vibration monitoring is critical. Its Type 4X and IP66 ratings make it suitable for washdown environments and outdoor installations. The CENELEC EN50014 rating for electrostatic dissipation allows safe installation in hazardous areas. Whether you are upgrading an existing monitoring system or specifying new equipment, this housing provides reliable protection.

Installation and Mounting Guidance

Proper installation is essential for accurate readings. The 3/4-14 NPT mounting thread ensures a secure fit. The probe cable length of 0.5 metre (20 in) should be routed carefully to avoid damage. The housing includes one 3/4-14 NPT fitting and two plugs for conduit connections. Always follow the manufacturer's manual for torque specifications and alignment to prevent measurement errors.

Maintenance and Reliability

Routine inspection of the housing and probe is recommended to ensure long-term reliability. Check the O-ring (Neoprene®) for wear and replace if necessary. Verify that all screws and fittings remain tight. The stainless steel components resist corrosion, but periodic cleaning with a mild detergent is acceptable. Regular maintenance minimizes downtime and extends service life.
