Basic information :
The working principle of the explosion-proof pressure switch is the action of the micro-dynamic switch caused by pure mechanical deformation.When the pressure increases, the effect on different sensing pressure components (diaphragm, corrugated pipe, the piston) produce deformation, will move up, by rail the spring, etc. The mechanical structure, eventually start at the top of the micro switch, the electrical signal output, set way from the function principle and divided into continuous displacement and force balance.
