Industry Applications
The 3300 XL 8 mm probe with connector protector supports radial vibration and axial position measurements. The selectable hazardous area approvals make it suitable for refineries, chemical plants, and gas processing facilities where explosive atmospheres may exist.

Installation & Setup Guidance
Mount the housing using the 3/4-14 NPT thread option. Ensure the standoff adapter (1.5 in) and probe penetration (6.6 in) match the machine's internal clearance. The aluminum body with 304 stainless steel sleeve provides corrosion resistance. Use the one 3/4-14 NPT plug for conduit entry. For hazardous areas, select the appropriate probe option with required approvals.
Maintenance & Reliability
Periodically inspect the housing for signs of corrosion, seal integrity, and cable condition. Verify that the dome cover and O-rings remain intact to maintain the CSA Type 4 enclosure rating. The assembly is designed for long-term reliability in harsh environments.
