Intrinsic safety is an energy limitation technology that mitigates ignition and explosion risk in hazardous atmospheres, where a spark or heat can easily cause ignition of an explosive vapor or dust.  Intrinsic safety deals with making a product incapable of causing an explosion, and is suited to measuring equipment, process control equipment, and signal conditioners.  This field is becoming more important to manufacturers as more jurisdictions require approvals for explosive atmosphere products, and certification of a product as intrinsically safe can help customers decide to use your product in hazardous locations.  WCL Corporation specializes in helping clients obtain intrinsic safety approvals for markets around the world.
