EARTHING CLAMP
With electronic monitoring system
ECS-R series electronic equipment provides earth connection of process equipment (road tankers, drums, IBCs, etc..) with real-time ground connection monitoring. The system monitors that connection to earth is obtained with a resistance lower than 10Ω.
ECS-R / ECS-RF
General Features
• Compact and rugged Ex-d enclosure suitable for ATEX Zone 1/21 installation
