Introduction to the 31000-28-10-00-133-03-02

When machinery vibration threatens uptime, the 31000-28-10-00-133-03-02 from Bently Nevada provides a durable mounting solution. This 31000 Proximity Probe Housing is designed to protect 3300 XL 8 mm probes in demanding industrial environments. With a 13.3-inch probe penetration and a 1.0-meter cable, it fits many standard installations. The housing is built to withstand harsh conditions, ensuring reliable monitoring.

Key Features and Technical Specifications

• Manufacturer: Bently Nevada
• Product Type: 31000 Proximity Probe Housing
• Probe Option: 3300 XL 8 mm probe with connector
• Probe Cable Length: 1.0 m (39 in)
• Probe Penetration: 13.3 in
• Mounting Thread: 3/4-14 NPT

The housing is made of glass-reinforced Polyphenylene Sulfide (PPS) thermoplastic with conductive fibers, offering excellent strength and static dissipation. The sleeve and retaining chain use AISI 304 stainless steel, while the outer sleeve and exterior screws are AISI 303 stainless steel for corrosion resistance. The Neoprene O-ring ensures a secure seal.

Durable Construction for Harsh Environments

This housing is certified to Type 4X by CSA and IP66, meaning it resists water jets and dust ingress. It also meets CENELEC EN50014 for electrostatic dissipation in hazardous areas. The housing withstands impacts of 4 Joules at extreme temperatures and 7 Joules at room temperature, as verified by BASEEFA and CSA. These ratings make it suitable for outdoor and washdown applications.

Installation and Mounting

Installation is straightforward with the 3/4-14 NPT mounting thread. The recommended torque for the retaining nut is 29.4 N·m (260 in·lb). Ensure the probe is properly inserted to the specified penetration depth. The included fittings—two plugs, one 3/4-14 NPT fitting, and a reducer—allow flexible cable routing. Always follow the manufacturer's guidelines for safe installation.

Maintenance and Reliability

Regular inspection of the housing and cable is recommended to maintain performance. Check for any signs of wear on the O-rings or threads. The stainless steel components resist corrosion, extending service life. Because the housing is not pressure-rated, avoid applying external pressure. For any pressure seal testing, contact the custom design department.

Compatibility and Integration

The 31000-28-10-00-133-03-02 is designed for use with Bently Nevada 3300 XL 8 mm proximity probes. It integrates seamlessly with existing monitoring systems. The 1.0-meter cable length suits many machine train configurations. For other cable lengths or probe options, refer to the official datasheet.
