    First, the working principle
       During operation, the isolation diaphragm and filling fluid on the high and low pressure sides transfer the process pressure to the filling fluid, and then the filling fluid transfers the pressure to the sensing diaphragm in the center of the sensor. The sensing diaphragm is a tensioned elastic element whose displacement varies with pressure (for GP gauge transmitters, atmospheric pressure is applied to the low pressure side of the sensing diaphragm). AP absolute pressure transmitter, the low pressure side always maintains a reference pressure. The maximum displacement of the sensing diaphragm is 0.004 inches (0.1 mm) and the amount of displacement is proportional to the pressure. The capacitive plates on both sides detect the position of the sensing diaphragm. The difference in capacitance between the sensing diaphragm and the capacitive plate is converted to a corresponding current, voltage or digital HART (High Speed ​​Addressable Remote Transmitter Data Highway) output signal.
