Industry Applications
The CSA Type 4 enclosure and explosion-proof rating ensure safe operation in classified areas. The 3300 XL 8 mm probe provides accurate displacement measurements, helping prevent costly unplanned downtime.
Installation & Setup Guidance
Mount the assembly using the 3/4-14 NPT thread option. Ensure the standoff adapter (3.0) is correctly positioned for proper probe penetration (3.9 in). Connect conduit via the provided fittings: one 3/4-14 NPT plug and one 3/4-14 to 1/2-14 NPT reducer. Use the included cable seal grip with appropriate grommets for cable sizes between 1/8 and 3/8 inches. Follow standard hazardous area installation practices for intrinsically safe circuits.
Maintenance & Reliability
Periodically inspect the housing for signs of corrosion or damage, especially in harsh environments. Verify that the O-rings and thread seal remain intact to maintain the CSA Type 4 enclosure rating. Clean the probe tip gently if debris accumulates. The aluminum body with 304 stainless steel sleeve offers resistance to corrosion in most industrial settings.
Selection Guide & Purchasing Advice
When ordering, confirm the probe cable length (1.0 m) and mounting thread (-02 for 3/4-14 NPT) match your installation requirements.
