ECS-R/ECS-RF – Earth Monitoring System

The EC-R and ECS-RF eclectronic devices provide earth connection of process equipment (IBC, drums, road tankers, etc) with real-time ground connection monitoring. The system monitors that the obtained connection to earth has an electrical resistance less or equal to 10 Ω, according to the ATEX Directive 2014/34/EU. The device can be equipped with two Ex i outputs for remote LEDs installed directly on the clamp (consensus green LED and non consensus red LED).

The ECS-RF device provides n.1 interlock SPST N.O contact with a safety integrity level up to SIL2 according to EN 50495.

Order code:
ECS-R: equipped with signalling contact
ECS-RF equipeed with SIL2 interlock contact
