したことを特徴とする圧力、差圧発信器。 Each measurement pressure is applied to a pair of barrier diaphragms provided on both sides of the detector body, and a center diaphragm provided inside the detector body is displaced by the movement of the sealed liquid due to the pressure difference, and this displacement In the differential pressure transmitter, each body chamber partitioned by the center diaphragm communicates with the sensor housing. A conductive hole is formed by a narrow hole consisting of a blind hole formed in the wall surface of the inner chamber of the body in the axial direction of the detector body, and a thick hole formed in the outer peripheral surface of the detector body and communicating with the narrow hole. A pressure and differential pressure transmitter characterized by the following configurations.
