Technical Specifications Breakdown

Key parameters for the 21000-34-05-30-039-04-02 are listed below for quick reference:

Industry Applications

This assembly is designed for externally mounted proximity probes on critical rotating equipment such as compressors, turbines, pumps, and motors. The CSA Type 4 enclosure and explosion-proof rating make it suitable for hazardous areas where flammable gases or dust may be present. The 3.0 in standoff adapter and 3.9 in probe penetration accommodate various bearing housing geometries.

Installation & Setup Guidance

When installing the 21000-34-05-30-039-04-02, ensure the mounting surface is clean and flat to maintain the seal integrity. Use a 3/4-14 NPT conduit connection for the cable entry. The standoff adapter length must be selected to position the probe tip at the correct gap from the shaft. Verify that the probe cable is not kinked or pinched during installation. The assembly includes a dome cover that screws into the body, providing easy access for probe adjustment or replacement.

Maintenance & Reliability

Regular inspection of the housing seals and conduit connections is recommended to maintain the enclosure rating. Check for signs of corrosion on the aluminum body or stainless steel sleeve, especially in corrosive environments. The 0-rings should be replaced if any leakage is suspected. The assembly is designed for long-term reliability with minimal maintenance, but periodic visual checks during routine machine inspections will help ensure continued protection.

Robust Protection for Critical Vibration Monitoring

For maintenance engineers working with rotating machinery, reliable vibration data is essential for early fault detection. The Bently Nevada 21000-34-05-30-039-04-02 Proximity Probe Housing Assembly provides a robust, sealed enclosure for the 3300 XL 8 mm proximity probe, ensuring consistent performance in harsh industrial environments. This assembly simplifies installation and protects the probe from physical damage, moisture, and contaminants, reducing unplanned downtime.

Compatibility & Integration

This housing assembly is compatible with Bently Nevada 3300 XL 8 mm proximity probes and is fully compliant with API 670 Standard for externally mounted proximity probe housings. The CSA certification ensures it meets North American hazardous location requirements. The 3/4-14 NPT mounting thread allows integration with standard conduit systems.
