With the development of social industrialization, the application range of differential pressure transmitters is becoming increasingly wide, and there are more and more problems encountered in production. In addition, the differences in the level of installation, use, and maintenance personnel make it difficult to quickly solve the problems that arise, which to some extent affects the normal progress of production and even threatens production safety.

Working Principle:The differential pressure from the double-sided pressure tube directly acts on the isolation diaphragm of the transmitter sensor on both sides, and is transmitted to the measuring element through the sealing liquid inside the diaphragm. The measuring element converts the measured differential pressure signal into the corresponding electrical signal and transmits it to the converter. After amplification and other processing, it becomes a standard electrical signal output.

Differential pressure transmitter measurement method:

1. Combined with the throttling element, measure the liquid flow rate using the differential pressure value generated before and after the throttling element.

2. Measure the height of the liquid by utilizing the pressure difference generated by its own gravity.

3. Directly measure the pressure difference of liquids in different pipelines and tanks.
