ことを特徴とする圧力・差圧発信器。 The detector body is equipped with a control diaphragm in the center that defines two internal chambers, and barrier diaphragms facing the backup surface on both sides of the control diaphragm. A communicating pressure transmission hole is provided, and the pressure transmission hole is constituted by two first passage holes each opening to the control diaphragm side and the barrier diaphragm side, and a second passage hole connecting these two passage holes, Among these, the second through hole extends in the radial direction of the detector body, and the first through hole extends in the axial direction, and the opening position of both the first through holes is in the middle of the second through hole. A pressure/differential pressure transmitter characterized by being positioned.
