What are the regulatory requirements for installing electromagnetic flowmeters and radar devices in explosive atmospheres?
Explosive atmosphere installation requires explosion-proof certified equipment, specialized junction boxes, and intrinsic safety procedures.
Installation in explosive atmospheres demands strict compliance with safety regulations to ensure intrinsic safety. LGF electromagnetic flowmeters and HZ-KSLF radar flowmeters require special explosion-proof certification and installation procedures in hazardous areas.
- Equipment must have appropriate explosion-proof ratings (ExdIICT6, ExiaIICT6) matching site hazard classifications
- All electrical connections use explosion-proof junction boxes with specified torque requirements
- Cable entries use explosion-proof cable glands with IP rating ≥IP65
- Independent grounding system with ground resistance ≤4Ω, reliably connected to plant ground grid
- Pre-installation gas detection to confirm no combustible gas concentration exceeds limits
- Use explosion-proof tools for installation work, prohibit spark generation
- Post-installation explosion-proof performance testing and acceptance
For intrinsically safe RTU devices EC32/EC60 series, safety barriers must be configured for signal isolation, ensuring loop energy remains within safe limits. Proper FMCW radar installation maintains both safety and measurement performance.
