Industry Applications: Protecting Critical Assets
The 21000-34-10-15-018-04-02 meets API 670 standards for externally mounted proximity probe housings, making it a trusted choice for compliance-driven applications. The 3300 XL 8 mm probe with connector protector ensures reliable signal transmission even in high-vibration environments.

Installation & Setup Guidance
When installing the 21000-34-10-15-018-04-02, ensure the mounting surface is clean and flat. Use the 3/4-14 NPT mounting thread for secure attachment. The standoff adapter length of 1.5 in and probe penetration of 1.8 in must be verified against the target shaft diameter and clearance. For explosion-proof installations, use only CA version housings with the appropriate E:00, E:01, E:02, or E:04 options. Always follow the manufacturer's torque specifications for the dome cover and conduit fittings.
Maintenance & Reliability
Periodically inspect the housing assembly for signs of corrosion or damage, especially in corrosive atmospheres. Check O-rings and thread seals for integrity. The aluminum body with 304 stainless steel sleeve offers durability. The 3300 XL 8 mm probe operates reliably from -51°C to +177°C, suitable for extreme environments. No internal disassembly is required for routine inspection.
