Industry Applications for Reliable Monitoring
This housing assembly is designed for externally mounted proximity probes on critical rotating equipment such as compressors, turbines, and pumps. The 3300 XL 8 mm probe with connector protector ensures consistent gap measurements, while the CSA Type 4 enclosure rating provides protection against dust and water ingress. The 1.8 in probe penetration suits standard bearing housing configurations.

Installation and Setup Guidance
Mount the housing using the 3/4-14 NPT thread option when no standoff adapter is required. Ensure the probe tip is properly positioned within the specified penetration depth. Use the included 3/4-14 NPT plug for unused conduit ports. For hazardous area installations, verify that the selected probe option matches the area classification.
Maintenance and Reliability
Periodically inspect the housing for signs of corrosion or mechanical damage, especially in harsh environments. Verify that the O-rings and thread seal remain intact to maintain the CSA Type 4 rating. The 304 stainless steel sleeve resists wear, but annual visual checks are recommended.
Robust Protection for Critical Vibration Monitoring
For maintenance engineers working with rotating machinery, reliable vibration data is non-negotiable. The Bently Nevada 21000-34-10-00-018-04-02 proximity probe housing assembly provides a rugged, field-proven enclosure for 8mm proximity probes in demanding environments. This assembly combines an aluminum body with a 304 stainless steel sleeve, offering corrosion resistance and mechanical strength for long-term service.

Compatibility and Integration
This assembly is fully compliant with the American Petroleum Institute's API 670 Standard for externally mounted proximity probe housings. It accepts 3300 XL 8 mm probes with connector protectors and is available with CSA explosion-proof approvals when ordered with appropriate options.
