とする差圧伝送器。 Among the differential pressure transmitters, the pressure of high-pressure and low-pressure fluids is received by two pressure-receiving diaphragms and transmitted to both sides of the semiconductor sensor via the sealed liquid to measure the differential pressure.
A differential pressure transmitter in which excessive differential pressure is protected by supporting one side of the pressure receiving diaphragm with the side surface of the pressure receiving part, characterized in that the passage of the pressure receiving part provided as a movement circuit for the sealed liquid has a shape other than circular. Differential pressure transmitter.
