Working principle of differential pressure level transmitter

Working principle of differential pressure level transmitter :

The working principle of the differential pressure level gauge is to divide a space with two sensitive components

into two chambers. When pressure is introduced into the two chambers respectively, the sensor generates 

displacement(or displacement tendency) under the action of the two pressures. The displacement is 

proportional to the pressure difference (differential pressure transmitter ) of the two chambers, which

is converted into a standard signal output that reflects the magnitude of the differential pressure.


Differential pressure level gauge for double-sided pressure guiding tube

The double-sided isolation diaphragm of the sensor is transmitted to the measuring component through 

the sealing liquid in the diaphragm, and the measuring component converts the measured differential 

pressure signal into a corresponding electrical signal and transmits it to the converter, and becomes a 

standard after being processed by amplification or the like. Electrical signal output. Several application 

measurement methods of the differential pressure level gauge: combined with the throttling element, the 

differential pressure value generated before and after the throttling element is used to measure the 

pressure difference between the liquid flow pipe and the tank liquid.
