Intrinsically Safe Instruments Help to Minimize Risks in Hazardous Locations
This paper covers approaches to designing and installing equipment in intrinsically safe systems that minimize the risk of explosions in hazardous environments.
Intrinsic safety is a concept that is used to prevent electrical equipment from causing explosions in hazardous environments. A hazardous environment is a location where potentially explosive mixtures of gases or fine powders are expected to exist. Electrical equipment has the potential of igniting these mixtures if sparks or high temperatures are generated during the operation of the equipment. In an intrinsically safe system, all of the equipment is designed and installed in such a way that it does not have enough energy to cause ignition of the potentially explosive gas mixture, even in a fault condition.
