Bently Nevada 31000-27-05-00-035-03-02 Proximity Probe Housing Assembly

Robust Protection for Critical Vibration Monitoring

The Bently Nevada 31000-27-05-00-035-03-02 is a rugged, field-proven 31000 Proximity Probe Housing designed to safeguard 3300 XL NSv probes in harsh industrial environments. This assembly ensures reliable, uninterrupted data collection for rotating machinery protection systems.

Technical Specifications Breakdown

Key parameters for the 31000-27-05-00-035-03-02 are listed below for quick reference:

Application Versatility for Challenging Environments

The wide temperature range of -51°C to +105°C ensures reliable performance in both Arctic and high-heat settings. By choosing the 31000-27-05-00-035-03-02, you reduce the risk of probe failure due to environmental stress, lowering overall maintenance costs.

Installation Guidance for Optimal Performance

When installing this housing, ensure the mounting thread (3/4-14 NPT) is properly engaged to maintain the environmental seal. The recommended torque for the retaining nut is 29.4 N·m (260 in·lb). The included fittings provide flexibility: two plugs, one 3/4-14 NPT fitting, one reducer, and a cable seal grip with grommets for cable sizes from 1/8 to 3/8 inches. Always verify that the O-rings (Neoprene and Viton) are clean and undamaged before assembly to preserve the seal integrity.

Maintenance and Reliability Considerations

Periodic inspection of the housing and O-rings is recommended, especially in high-vibration or corrosive environments. The housing's impact strength has been certified by BASEEFA to withstand 4 Joule impacts at extreme temperatures, and CSA verified 7 Joule impacts at room temperature. The conductive fiber-filled PPS material provides electrostatic dissipation, reducing ignition risk in hazardous areas. While the housing is not designed for internal or external pressure, its robust construction ensures long-term reliability for standard proximity probe applications.

Selection Guide and Purchasing Advice

When selecting a probe housing, match the probe option, cable length, and penetration to your specific machine geometry. The 31000-27-05-00-035-03-02 is configured for a 3300 XL NSv probe with a 0.5 m cable and 3.5 in penetration. For applications requiring a standoff adapter, note that this option is not included.
