Bently Nevada 21000-34-00-30-065-03-02 Proximity Probe Housing Assembly

Technical Specifications Breakdown

Key parameters for the 21000-34-00-30-065-03-02 are listed below for quick reference:

Industry Applications

The 6.5-inch probe penetration and 3.0 standoff adapter allow precise positioning relative to the shaft target, while the 3/4-14 NPT mounting thread ensures a secure, leak-proof installation. The selectable hazardous area approvals make it suitable for refineries, chemical plants, and gas processing facilities where explosive atmospheres are present.

Installation & Setup Guidance

When installing the 21000-34-00-30-065-03-02, first verify that the mounting surface is clean and flat. Apply thread sealant to the 3/4-14 NPT mounting thread to prevent leakage. Use the provided fitting kit to connect conduit: the 3/4-14 NPT plug seals unused ports, the reducer adapts to 1/2-14 NPT, and the cable seal grip accommodates cable diameters from 1/8 to 3/8 inches. Route the probe cable through the grip and tighten the grommet to maintain the enclosure seal. Ensure the probe tip does not contact the shaft during installation.

Maintenance & Reliability

Periodically inspect the housing for signs of corrosion, especially in wet or corrosive environments. The aluminum body with 304 stainless steel sleeve offers good resistance, but regular checks extend service life. Verify that all conduit fittings remain tight and that the cable seal grip maintains its compression. Replace O-rings if leakage is detected. The CSA Type 4 rating ensures protection against dust and water ingress, but verify the enclosure integrity after any maintenance.

Robust Protection for Vibration Monitoring in Hazardous Environments

In rotating machinery monitoring, the probe housing is the first line of defense against environmental contaminants and mechanical damage. The Bently Nevada 21000-34-00-30-065-03-02 proximity probe housing assembly provides a rugged, explosion-proof enclosure for 8 mm proximity probes, ensuring reliable vibration and position measurements in the harshest industrial settings.

Compatibility & Integration

This housing is designed for use with Bently Nevada 3300 XL 8 mm proximity probes (probe not included in this configuration). The assembly is fully compliant with API 670, making it a standard choice for vibration monitoring in the oil and gas industry. The CSA Type 4 enclosure and explosion-proof rating allow installation in hazardous areas without additional protection.

Selection Guide & Purchasing Advice

When ordering the 21000-34-00-30-065-03-02, verify that the probe penetration and standoff adapter match your shaft clearance requirements. The 6.5-inch penetration and 3.0 standoff are common for many turbine and compressor applications. If you need a different penetration or standoff, consult the Bently Nevada ordering guide for alternative suffix codes.
