Industry Applications for the 21000 Housing Assembly
This housing assembly is designed for externally mounted proximity probes in rotating machinery such as turbines, compressors, and pumps. The 1.5 in standoff adapter and 6.5 in probe penetration allow precise positioning relative to the shaft. The CSA Type 4 enclosure rating and API 670 compliance ensure reliable operation in harsh industrial environments.

Installation and Setup Guidance
When installing the 21000-34-00-15-065-04-02, ensure the mounting thread (3/4-14 NPT) is properly sealed to maintain the explosion-proof rating. The aluminum body with 304 stainless steel sleeve provides corrosion resistance. Use the included 3/4-14 NPT plug for unused ports. Verify that the probe cable length (1.0 m) is sufficient for your routing needs.
Maintenance and Reliability
Periodically inspect the housing for signs of corrosion or damage, especially in wet or corrosive atmospheres. Check O-rings and seals during routine maintenance. The assembly's robust construction minimizes drift, but verify probe gap settings per Bently Nevada guidelines.

Compatibility and Integration
The 21000 housing is compatible with Bently Nevada 3300 XL 8 mm proximity probes. It integrates with monitoring systems that accept standard proximity probe inputs. The CSA explosion-proof rating allows installation in hazardous areas when ordered with appropriate options.
Selection Guide and Purchasing Advice
When selecting a housing assembly, consider probe penetration and standoff adapter length to match your machine geometry.
