にしたことを特徴とする差圧伝送器。A center diaphragm is disposed inside a main body having an internal chamber so as to divide the internal chamber into two, a pair of insulating support members are disposed to face each other with the center diaphragm sandwiched between them, and these insulating support members Detecting means for detecting the amount of displacement of the center diaphragm is provided, pressure receiving elements are provided on the sides of the main body, and the insides of these pressure receiving elements are communicated with the internal chamber partitioned by the center diaphragm. , in a differential pressure transmitter in which a space closed by the pressure receiving element is filled with a sealed fluid, the Young's modulus of the material forming at least one of the insulating support member and the sensing means is determined by the Young's modulus of the material forming the main body. A differential pressure transmitter, characterized in that the modulus is set to be substantially equal to or larger than Young's modulus, thereby preventing a change in the distance between the center diaphragm and the detection means due to a change in static pressure.
