A pressure switch is a simple pressure control device that can emit an alarm or control signal when the measured pressure reaches the rated value. The working principle of a 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 connector is pushed through the connecting guide rod to connect or disconnect. When the pressure drops to or rises to the rated recovery value, the disc instantly resets, and the switch automatically resets. In other words, when the measured pressure exceeds the rated value, the free end of the elastic element shifts, Directly or after comparison, push the switch element to change its on/off state, achieving the purpose of controlling the measured pressure. The elastic components used for pressure switches include single coil spring tubes, diaphragms, bellows, and other components. Switch elements include magnetic switch, Mercury switch, microswitch, etc. The German DUNGS pressure switch and pressure monitor LGW A4 are adjustable pressure monitors suitable for combustion equipment Applicable to the opening, closing, and switching of the circuit when the actual pressure value changes to the adjusted switching point (rated value) The switch point can be adjusted on the dial for convenience and time saving, without the need for a pressure gauge The integrated measurement nozzle on the metal casing is a standard configuration Suitable for air, flue gas, exhaust gas, and other non corrosive gases. |
