。The casing, in which a part of the sensor that detects differential pressure is installed, has a seal diaphragm that seals the enclosed liquid that transmits pressure to the sensor part, and an introduction part that introduces gas or liquid on the high pressure side and the low pressure side, respectively, on both sides. A port and an isolation diaphragm for isolating the gas or liquid are formed in the center of the interior, and a valve shaft is connected to the isolation diaphragm and perpendicular to the isolation diaphragm, and the inlet is connected to both ends of the valve shaft. A differential pressure transmitter, characterized in that a valve element is provided for opening and closing each port, and the valve element closes the introduction port to prevent one-sided pressure from being applied to a seal diaphragm.
