General pressure transmitters are suitable for measuring gases, liquids, and other media that are compatible with the material of the transmitter. Today we will talk to you about how pressure transmitters measure gas media. The pressure transmitter can measure absolute, negative and gauge pressure for gases. The pressure of the gas is simply the pressure of the gas itself on the wall of the container. Many physical and chemical properties are related to pressure, such as the boiling point, melting point and vapor pressure of gases, thermodynamics, kinetics, etc. Therefore, pressure transmitters are of great significance for the measurement of pressure gases. When the gas in the pipe or vessel presses the pressure transmitter, the resistance value of the bridge wall of the pressure transmitter changes (piezoresistive effect), which generates a differential voltage signal, which is finally converted into a standard current, voltage or digital signal after passing through a special amplifier. This is one of the processes by which a pressure transmitter measures gases. For the measurement of gases, especially steam or other high-temperature gases, it is necessary to be careful not to let the temperature of the high-temperature gas exceed the operating temperature range of the pressure transmitter, and if necessary, it is a good choice to add a cooling device to the pressure transmitter.
