The power supply part: (DC 220V through the switching circuit, converted to) the required DC voltage, and then supplied to the required circuit through the voltage regulator circuit, or (24V) DC voltage directly supplied to the required circuit through the voltage regulator circuit.
Signal part: the pressure of the measured medium is transmitted to the sensor's pressure sensitive diaphragm through the pressure interface. The sensor will amplify the induced electric signal, convert it to V/A, send it to the CPU for processing, set the display number, control the switch output, and provide Analog or digital output for pressure display, control and transmission.
