加えるようにした差圧伝送器。A central diaphragm for overpressure compensation is arranged in a compensation chamber provided inside the main body, and a pressure receiving chamber formed between pressure receiving diaphragms on both sides of the main body and the main body, and the compensation chamber divided by the center diaphragm are separated. In the differential pressure transmitter, the chambers are communicated with each other, and a measured pressure is applied to the pressure-receiving element through an incompressible fluid filled in the chambers, and a signal corresponding to the pressure difference applied to the pressure-receiving diaphragm is generated. A pair of diaphragms having the same shape are used as the heart diaphragm, and these diaphragms are arranged in the compensation chamber so that the same sides of the corrugations face each other, and an incompressible fluid is filled between these diaphragms, and each of these diaphragms and the pressure receiving chamber are A differential pressure transmitter configured to apply fluid pressure in a chamber between the pressure receiving element and the pressure receiving element.
