UE压力开关H117-700、H117-702（US UE pressure switch H117-700, H117-702 ）

US UE pressure switch H117-700, H117-702, H117-704, H117-706 Application  UE  117 series vacuum switch is widely used in water supply and sewage treatment, pump and paper making, food and beverage, steel plant, aluminum plant, petrochemical industry and medicine, etc.  Working principle  The working principle of the pressure switch is that when the pressure in the system is higher or lower than the rated safety pressure, the disc in the sensor moves instantaneously, and the switch joint is connected or disconnected by connecting the guide rod. When the pressure drops to Or when the rated recovery value is raised, the disc resets instantaneously and the switch automatically resets, or in simple terms, when the measured pressure exceeds the rated value, the free end of the elastic element is displaced, and the switch element is pushed directly or after comparison to change the switch. The on-off state of the component can achieve the purpose of controlling the measured pressure. The elastic components used in the pressure switch include single coil spring tube, diaphragm, bellows and so on.
