Industrial Applications for Reliable Vibration Monitoring
This housing assembly is purpose-built for use in rotating machinery such as turbines, compressors, and pumps. The 3300 XL 8 mm probe provides precise radial vibration and position measurements. The API 670 compliance ensures it meets industry standards for externally mounted proximity probe housings.

Installation and Setup Guidance
Proper installation is critical for accurate readings. The 3/4-14 NPT mounting thread provides a secure, leak-proof connection. The included fittings allow flexible conduit routing: a 3/4-14 NPT plug, a reducer to 1/2-14 NPT, and a cable seal grip with grommets for cable diameters from 1/8 to 3/8 inches. Ensure the probe penetration (D dimension) of 9.8 in is set correctly to achieve the optimal gap. The standoff adapter length of 1.5 in (38 mm) positions the probe correctly relative to the shaft.
Maintenance and Reliability
Routine inspection of the housing and probe assembly is recommended. Check the O-rings and thread seal for integrity during every maintenance cycle. The aluminum body with 304 stainless steel sleeve resists corrosion in harsh environments. For hazardous area installations, verify that the CSA Type 4 enclosure rating and explosion-proof certifications are maintained after any service. Always follow the manufacturer's guidelines for safe handling.
