3 PHASE WATER PUMP CONTROLLED BY PRESSURE SWITCH

3PHASE WATER PUMP CONTROLLED BY PRESSURE SWITCH How water pump works Water pump Pressure switch Start stop water pump Automatic water pump Apressure switchis a form ofswitchthat operates anelectrical contactwhen a certain set fluidpressurehas been reached on its input. The switch may be designed to make contact either on pressure rise or on pressure fall. Pressure switches are widely used in industry to automatically supervise and control systems that use pressurized fluids. Another type of pressure switch detects mechanical force; for example, a pressuresensitive mat is used to automatically open doors on commercial buildings. Such sensors are also used insecurity alarmapplications such as pressure sensitive floors. A pressure switch for sensing fluid pressure contains a capsule, bellows, Bourdon tube, diaphragm or piston element that deforms or displaces proportionally to the applied pressure. The resulting motion is applied, either directly or through amplifying l
