Bently Nevada 21000-34-00-30-095-04-02 Proximity Probe Housing Assembly

Technical Specifications Breakdown

Key parameters for the 21000-34-00-30-095-04-02 are listed below for quick reference:

Industry Applications

Turbine and Compressor Monitoring

Its CSA Type 4 enclosure rating and explosion-proof certification make it suitable for hazardous areas where flammable gases or vapors may be present.

Pump and Motor Protection

For critical pumps and large electric motors, this housing provides a secure, repeatable mounting solution for 8 mm proximity probes. The 3 in standoff adapter and 9.5 in probe penetration allow precise positioning to monitor shaft vibration and axial position, helping avoid costly bearing failures.

Installation & Setup Guidance

When installing the 21000-34-00-30-095-04-02, ensure the mounting surface is clean and flat. The 3/4-14 NPT mounting thread requires a compatible conduit connection. Use the included 3/4-14 NPT plug for unused ports to maintain the enclosure seal. The probe cable length is specified as not required (option 00), so plan for external cabling through the conduit ports. Verify that the probe tip gap is set according to the machinery manufacturer's specifications before final tightening.

Maintenance & Reliability

Periodically inspect the housing assembly for signs of corrosion or damage, especially in corrosive environments. Check that all O-rings and seals are intact to preserve the explosion-proof rating. The aluminum body with 304 stainless steel sleeve offers resistance to environmental stress. No internal adjustments are needed; the assembly is designed for long-term, maintenance-free operation.

Robust Protection for Critical Vibration Monitoring

When monitoring rotating machinery in harsh industrial environments, the housing that protects your proximity probe is just as critical as the probe itself. The Bently Nevada 21000-34-00-30-095-04-02 Proximity Probe Housing Assembly provides a durable, explosion-proof enclosure designed to meet the demanding requirements of API 670 standards. This assembly ensures reliable, accurate vibration and position measurements in hazardous areas, reducing unplanned downtime and maintenance costs.

Selection Guide & Purchasing Advice

When selecting a proximity probe housing, match the suffix codes to your specific probe and mounting requirements. The 21000-34-00-30-095-04-02 is configured with a 3300 XL 8 mm probe, 3 in standoff, and 9.5 in penetration. For different probe lengths or mounting threads, consult the ordering information.
