The gas pressure is the pressure of the gas donor wall. It is the macroscopic performance of a large number of molecules continuously striking the wall, and is an important parameter used to describe the state of the system. In addition, the gas pressure is a physical quantity that reflects the state of motion of the gas and its energy. According to the principle of action and the physical meaning of its representation, it is divided into static pressure and dynamic pressure. The sum of them is called full pressure. In many physical and chemical properties, such as point, boiling point, and vapor pressure, almost all are related to pressure. Pressure is also an important factor in chemical thermodynamics and chemical kinetics research. Therefore, the measurement of pressure is of great significance.
Under the appropriate pressure, the gas can be pressed into a small space. The gas in the space increases with the increase of the pressure, and the gas is compressed. On the contrary, if a certain amount is The gas passes into a space larger than the volume it normally occupies, and the gas always fills the entire space evenly, but the pressure there will be lower than the pressure of the original gas charged, so the gas expands. . The gas does not have a certain shape, and its volume is also determined by the volume of the container. Therefore, when discussing and studying the mechanical problems related to gases, it is not enough to mention the weight of it. It is often necessary to mention the volume of it. Severity is a physical quantity indicating the weight of a gas contained in a unit volume.
The pressure sensor is used to provide a solution to the gas pressure measurement. The pressure sensor for gas pressure measurement is mainly used to measure the gas pressure. It can be used for blood pressure, wind pressure, pipeline gas, etc. Aspects of pressure measurement. Its performance is stable and reliable, mainly for physical experiments related to gas pressure, such as gas law, and can also measure dry, non-corrosive gas pressure in biological and chemical experiments.
