Industry Applications
The explosion-proof design (CSA rated) allows installation in Class I hazardous areas. The 2-inch standoff adapter and 3-inch probe penetration accommodate standard mounting configurations, ensuring reliable shaft displacement measurements.
Installation & Setup Guidance
Mount the housing securely using the 3/4-14 NPT thread. Ensure the probe tip is properly positioned per manufacturer guidelines. The assembly includes a dome cover, threaded ports for conduit, and O-rings for environmental sealing. Use the provided thread seal to prevent leakage. Verify the probe cable length (1.0 m) is sufficient for routing to the monitor.
Maintenance & Reliability
Inspect the housing periodically for corrosion or damage, especially in harsh environments. The aluminum body with 304 stainless steel sleeve offers durability. Check O-rings and seals during routine maintenance to maintain the CSA Type 4 enclosure rating. No internal adjustments are required.
