Working principle of pressure transmitter
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 4-20mA standard current output signal linearly corresponding to the liquid level pressure of the measured medium (liquid) through V / a voltage and current.
