Working principle

When working, the high and low pressure side of the isolation membrane and the filling liquid transfer the process pressure to the center of the filling liquid, the center of the filling liquid will be transferred to the pressure δ &mdash. The sensing membrane is a elastic element of tension, the displacement changing as differential pressure (atmospheric pressure gauge transmitter for GP, as applied in the low voltage side of the sensing membrane.). AP absolute pressure transmitter, low pressure side always maintains a reference pressure. The maximum displacement of the sensing diaphragm is 0.004 inches (0.10 mm). And the displacement is proportional to the pressure. The capacitance plate on both sides detects the position of the sensing diaphragm. The capacitance difference between the sensing film and the capacitance plate is converted to the desired current, voltage or digital HART (high speed addressable remote transmitter data highway) output signal.
