The process pressure is transmitted through the isolation membrane on both sides or one side, and the filling liquidδThe central measuring diaphragm of the chamber is a tensioned elastic element that produces corresponding deformation displacement for the pressure difference acting on it on both sides. Its displacement is proportional to the differential pressure, and the maximum displacement is about0.1mmThis displacement is transformed into a differential capacitor formed on the capacitor plate, which is converted into a two-wire system by electronic circuits4~20mA　DCOutput signal.
