Bently Nevada 31000-28-05-00-025-01-02 Proximity Probe Housing

Technical Specifications Breakdown

Key parameters for the 31000-28-05-00-025-01-02 are listed below for quick reference:

Harsh Environment Applications

The Type 4X and IP66 ratings make it suitable for outdoor installations, washdown areas, and chemical processing plants. The glass-reinforced PPS construction resists chemical attack and maintains structural integrity across a wide temperature range. Typical applications include:

• Steam turbine bearing vibration monitoring – withstands high temperatures and oil mist.
• Compressor shaft proximity measurement – IP66 protection prevents ingress in humid compressor stations.
• Pump condition monitoring – rugged housing protects against accidental impacts (7 Joule impact strength certified by CSA).

Installation Guidance

When installing this housing, ensure the mounting thread (3/4-14 NPT) is properly sealed to maintain the IP66 rating. The recommended torque for the retaining nut is 29.4 N·m (260 in·lb). Use the provided 3/4-14 NPT fitting and two plugs for cable entry. The housing supports a static load of 912 N (205 lb) when mounted per test conditions. Always verify that the grounding liner is installed to meet CENELEC EN50014 electrostatic dissipation requirements.

Maintenance & Reliability

Periodically inspect the O-ring (Neoprene) for signs of wear or compression set. Check that all exterior screws (AISI 303 stainless steel) remain tight. The housing impact strength has been certified by BASEEFA to withstand 4 Joule impacts at extreme temperatures (-39°C and +115°C). For long-term reliability, replace the O-ring if the housing is disassembled. No internal adjustments are required.

Robust Protection for Critical Vibration Monitoring

Industrial rotating machinery demands reliable vibration monitoring to prevent catastrophic failures. The Bently Nevada 31000-28-05-00-025-01-02 proximity probe housing provides a rugged, environmentally sealed enclosure for 3300 XL 8 mm probes. Designed for harsh conditions, this housing ensures consistent performance in applications ranging from steam turbines to compressors.

Selection Guide & Purchasing Advice

When selecting a replacement or new housing, verify the probe cable length (0.5 metre) and probe penetration (2.5 in) match your installation requirements. The 31000-28-05-00-025-01-02 includes a 3300 XL 8 mm probe with multiple approvals. For applications needing a standoff adapter, order option 00 (none included). Please verify current lifecycle status and availability with AutoDCSTech before ordering.
