Electronic equipment is required to carry out certain functions in potentially explosive atmospheres. To prevent potential ignition through a spark or arc in these environments, all components must be selected very carefully. These components known as Ex-ATEX (Explosion Proof) Meder products are available from Koloona Industries .
Components meeting these requirements are generally referred to as intrinsically safe. These components must be tested so that they will not become an ignition point, when subjected to short circuits or adjacent component failures. They must also switch to a defined state when subjected to overload conditions.
Generally, intrinsically safe approved components find applications in the mining industry, chemical processing plants, refineries, power stations and high dust producing plants. These components are suitable for all kinds of potentially flammable atmospheres.
