The smart differential pressure transmitter is a pressure sensor assembly used to prevent the medium in the pipeline from directly entering the transmitter, which is connected to the transmitter by a capillary tube filled with fluid. It is used to measure the level, flow and pressure of liquids, gases or vapors, and then converts them into a 4-20mA DC signal output.
