Bently Nevada 21000-34-05-00-028-04-02 Proximity Probe Housing Assembly

Technical Specifications Breakdown

Key parameters for the 21000-34-05-00-028-04-02 are listed below for quick reference:

Industry Applications for Enhanced Reliability

Steam Turbine and Compressor Monitoring

In power generation and oil & gas facilities, steam turbines and centrifugal compressors operate at high speeds and temperatures. The 21000 housing assembly, with its aluminum body and 304 stainless steel sleeve, withstands extreme thermal cycling while protecting the probe from moisture and debris. The 0.5 m cable length suits tight installations near bearing housings.

Hazardous Area Compliance

The selectable hazardous area approvals allow engineers to match the probe to zone-specific requirements without changing the housing.

Installation and Setup Guidance

Mount the 21000-34-05-00-028-04-02 using the 3/4-14 NPT thread into a compatible conduit or standoff. Ensure the probe penetration of 2.8 in aligns with the target shaft gap per manufacturer guidelines. Use the included 3/4-14 NPT plug to seal unused ports. Verify that the dome cover is fully tightened and O-rings are seated properly to maintain the CSA Type 4 enclosure rating.

Maintenance and Reliability

Periodically inspect the housing for corrosion, especially in coastal or chemically aggressive environments. Check that the dome cover and conduit fittings remain secure. The 304 stainless steel sleeve resists wear, but verify the probe tip clearance during routine outages. Replace O-rings if any leakage is detected.

Robust Protection for Critical Vibration Monitoring

Industrial rotating machinery demands precise and reliable vibration monitoring to prevent catastrophic failures. The Bently Nevada 21000-34-05-00-028-04-02 Proximity Probe Housing Assembly provides a rugged, environmentally sealed enclosure for the 3300 XL 8 mm proximity probe, ensuring accurate shaft displacement measurements even in hazardous areas. This assembly is engineered to meet API 670 standards for externally mounted probe housings, delivering long-term stability in harsh conditions.

Compatibility and Integration

This housing assembly is designed for the 3300 XL 8 mm probe series. It integrates with Bently Nevada monitoring systems such as the 3500 and 3300 racks. The reverse mount probe configuration simplifies installation in confined spaces. Always confirm probe part number compatibility with your existing system before ordering.

Selection Guide and Purchasing Advice

When ordering the 21000-34-05-00-028-04-02 from AutoDCSTech, verify that the probe cable length (0.5 m) and penetration (2.8 in) match your machine train geometry. For installations requiring a standoff adapter, select the appropriate suffix code. AutoDCSTech stocks new, factory-sealed units with a 12-month warranty. Please confirm current lifecycle status and availability before ordering.
