摘要： The invention refers to an explosion protection system for electrical apparatuses and machineries, such as manipulators or industrial robots, located in hazardous environments, i.e. environments containing explosive concentrations of inflammable gases, dusts or vapours, comprising means for applying internal pressurized air into an explosion proof enclosure and that has a purging system and electrical components, such as motors, relays, IC-boards, cables etc. The invention is achieved by, that a flow-and pressure sensor is arranged as an integrated unit and designed to stand high dynamic forces by having low inertia, balanced arrangement of moving parts and a movement guide, e.g. an axle with a support guide, with low friction.
