Measuring principle of   4 20ma pressure transmitter

Process pressure by both sides or one side of the isolation membrane and pouring the liquid to the center of the room six measuring diaphragm, diaphragm is an elastic element of tension, effect on the pressure difference on both sides of the (directed for GP gauge pressure transmitter, the atmospheric pressure in the center of the low voltage side of the diaphragm; for AP absolute pressure transmitter, the low voltage side always maintain a reference pressure) to generate the corresponding deformation displacement, displacement is proportional to the differential pressure, the maximum displacement of about 0.10 mm, the displacement on the capacitance board form differential capacitance, differential capacitance by electronic circuit convert into two wire 4 ~ 20 ma DC signal output.
