Industry Applications
This housing assembly is engineered for continuous vibration monitoring on compressors, turbines, pumps, and fans. The 3300 XL 8 mm probe with connector protector suits hazardous area installations, while the 1.5 in standoff adapter and 6.5 in probe penetration accommodate various casing thicknesses. The CSA Type 4 enclosure rating ensures protection against dust and water ingress, reducing false readings and maintenance interventions.

Installation & Setup Guidance
Mount the housing using the 3/4-14 NPT thread option. Ensure the probe tip is positioned per manufacturer gap settings for optimal linear range. The 0.5 m probe cable connects to extension cables via the connector protector. Use the supplied 3/4-14 NPT plug for unused conduit ports to maintain enclosure integrity. Always verify hazardous area approvals match site classification before installation.
Maintenance & Reliability
The aluminum body with 304 stainless steel sleeve resists corrosion in most industrial atmospheres. Periodically inspect the dome cover O-rings and conduit seals for damage. The connector protector shields the probe connector from moisture and debris. No internal adjustments are required; the assembly is designed for long-term, maintenance-free operation under normal conditions.
Robust Vibration Monitoring for Critical Machinery
Maintaining uptime on rotating equipment demands reliable, accurate vibration sensing. The Bently Nevada 21000-34-05-15-065-04-02 proximity probe housing assembly provides a rugged, sealed enclosure for 3300 XL 8 mm probes in harsh industrial environments. Designed for external mounting per API 670, this assembly simplifies installation and protects the probe from contaminants, ensuring consistent data for predictive maintenance.
