  • working principle
    When the pressure signal acts on the sensor, the pressure sensor converts the pressure signal into an electrical signal, which is amplified by differential amplification and output amplifier, and finally converted into a linear relationship with the liquid pressure of the measured medium (liquid) by the V/A voltage current. 4-20mA standard current output signal.
