How do intrinsically safe barriers work
WebIn Intrinsically safe circuits, a safety barrier is used between the “safe area” and the “hazardous area”, so that any fault that generates a high energy level (and sparks), would … WebHence, non-simple devices have the entity parameters and must be certified as “Intrinsically safe” for use in the hazardous area. e.g. Transmitter; Associated apparatus. A device that is installed in a safe area and works as an interface between a hazardous location and a safe location. e.g. Intrinsic safety barrier
