The single and double flange differential pressure transmitter is composed of a differential pressure transmitter, a capillary tube and a flange with a sealing diaphragm. The function of the sealing diaphragm is to prevent the medium in the pipeline from directly entering the differential pressure transmitter. It is connected to the transmitter by a capillary filled with liquid (usually silicone oil). When the diaphragm is compressed, it will deform slightly. , The deformation displacement or frequency is transmitted to the transmitter through the liquid of the capillary tube, which is processed by the transmitter and converted into an output signal.
