Functional Instruction

Sealed diaphragms are used for prevention of medium in the pipelines directly entering pressure

sensors assembly in the differential pressure transmitters, which are connected with transmitters

with the help of capillary tubes filling fluid inside.

   

HHGP/DP Smart diaphragm sealed differential pressure transmitters are used for measuring flow rate, density 

and pressure of gas, liquid and steam , and then outputs  4~20mA DC power signal corresponding 

to measured differential pressure. They can communicate with Hart system, remote set and monitor can be set.
