1. Explosion proof construction is a totally enclosed construction such that even if an explosive gas exDlodes inside the container the container will withstand the force of the explosion and there is no danger of ignition by external explosive gases Our differential pressure Switches manufactured under this policy are used in Dressure measurements where infammable gas or the infammable gas vapors may exist in factories and business offices Indicates the temperature class HB Group classification ll B group includes hydrogen gas Symbol indicating explosion proof construction Symbol indicating exDplosion proof construction Group classification T IL II Explosion proof electrical equipment a2.
