Working principle of electronic pressure switch:
When the pressure inside the medium is higher or lower than the rated safety pressure, the disc in the sensor moves instantaneously. 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 moves, and the switch element is directly or after comparison, pushed, Change the on/off state of the switching element to achieve the purpose of controlling the measured pressure. The elastic components used in electronic pressure switches include single coil spring tubes, diaphragms, diaphragm boxes, and corrugated tubes. Switching components include magnetic switches, mercury switches, micro switches, etc.
Compared with ordinary pressure switches, electronic pressure switches currently have the following characteristics:
(1) Model recognition technology was adopted to overcome the abnormal pump swing caused by the action of the pressure switch when the pressure of the existing pressure switch is instantaneously ultra-low
(2) Added a process selection switch. Different thresholds can be set for the side connected tank process and the sealed process. The threshold set for the side connected tank process can be appropriately reduced, thus solving the problem of the pressure switch not being able to be used in the side connected tank process
(3) Added a calibration button. When verifying the intelligent electronic pressure switch, simply press the "calibration button", and the microcomputer will automatically remember the current pressure value and use it as the set value for the "intelligent electronic pressure switch", thus achieving intelligent calibration of the pressure switch
