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.
