How pressure transmitters work

How many applications require the use of pressure transmitters? How many types of pressure transmitters are there? A pressure transmitter suitable for one application is often not suitable for another because the same pressure transmitter is often not designed to withstand the operating conditions of different applications. So how does a pressure transmitter work? Next, the editor of Shanghai Ruicheng Electronic Instrument Co., Ltd. will give you a brief introduction. Many pressure transmitters work by supplying power, responding to changes in pressure and temperature. For temperature fluctuations, many transmitters have a normal operating range. If operating outside this range, the transmitter is likely to malfunction. In extreme cases, even if the pressure itself is constant, the electrical output signal of the transmitter may change due to temperature changes. Because when the temperature rises or falls, the material of the pressure transmitter will thermally expand and contract, and the geometry, mechanical properties, and electrical properties will change, resulting in measurement errors. As you might expect, pressure is an important factor affecting the performance of another transmitter. Sudden extreme pressure changes (sometimes referred to as 'pressure spikes') can destroy transmitters that do not have the corresponding pressure tolerance. In this case, all system processes will be aborted whether the gears are clogged or the valves are clogged. Of course, not all applications experience stress spikes. However, if it is such an application, it will require special transmitters designed for extreme environments, capable of taking on such tasks, differential pressure transmitters suitable for monitoring gas and liquid pressures. It should be noted that there are many other factors that affect the measurement accuracy of pressure transmitters, such as configuration, electromagnetic interference, linearity, etc.
