Bently Nevada 31000-28-05-50-050-03-02 Proximity Probe Housing Assembly

Technical Specifications Breakdown

Key parameters for the 31000-28-05-50-050-03-02 are listed below for quick reference:

Industry Applications

The 3300 XL 8 mm probe compatibility ensures accurate shaft displacement and vibration measurements. The Type 4X and IP66 ratings make it suitable for outdoor installations, chemical plants, and offshore platforms where moisture and corrosion are constant threats. The robust glass-reinforced PPS housing withstands impacts up to 7 Joules at room temperature, reducing the risk of damage from accidental blows.

Installation & Setup Guidance

Mount the housing using the 3/4-14 NPT mounting thread option. Ensure the standoff adapter is correctly set to 5.0 inches and the probe penetration is adjusted to 5.0 inches for optimal clearance. The included fittings allow for a secure cable entry: use the 3/4-14 to 1/2-14 NPT SST reducer if needed, and select the appropriate grommet for your cable diameter (1/8 to 3/8 inches). Tighten the retaining nut to the recommended torque of 29.4 N·m (260 in·lb) to maintain the seal. Note that the housing is not designed to resist internal or external pressure; contact Bently Nevada for pressure seal testing if required.

Maintenance & Reliability

Periodically inspect the housing for signs of physical damage or corrosion, especially in harsh environments. Verify that the O-rings (Neoprene) remain pliable and free of cracks. The AISI 304 and 303 stainless steel components resist rust, but regular cleaning is recommended to maintain the Type 4X/IP66 seal integrity. The housing impact strength has been certified to withstand 4 Joule impacts at extreme temperatures (-39°C and +115°C), ensuring reliable operation in thermal cycling conditions.

Robust Protection for Critical Vibration Monitoring

The Bently Nevada 31000-28-05-50-050-03-02 is a precision-engineered proximity probe housing assembly designed to safeguard 3300 XL 8 mm probes in demanding industrial applications. This housing provides a sealed, impact-resistant enclosure that maintains signal integrity while withstanding harsh environmental conditions.

Compatibility & Integration

This housing is specifically designed for the Bently Nevada 3300 XL 8 mm probe (probe option 28). The multiple approvals on the probe option ensure compliance with various international standards. Always verify that the probe cable length of 0.5 m matches your installation requirements.

Selection Guide & Purchasing Advice

When ordering the 31000-28-05-50-050-03-02, confirm that the standoff adapter and probe penetration options (both 5.0 inches) suit your machine geometry. The mounting thread option 02 (3/4-14 NPT) is required when using the standoff adapter. For applications requiring higher pressure sealing, contact the custom design department.
