压力传感器应用及选用原则（Application and selection principle of pressure sensors） Application and selection principle of pressure sensors Types of pressure sensor range, its performance also have great differences, in real life, the pressure sensor in the application is very extensive, according to the specific use of the environment, conditions and requirements, pressure sensor is economical and reasonable to choose the more suitable, can play a multiplier effect. To understand the direction of application of pressure sensors in different fields, it is necessary to understand the performance parameters and selection principle of pressure sensors first. The pressure sensor (pressure sensor principle) is the most mature sensor sensor technology, market sales, ranking the first sensor, and the annual growth rate of 2%, and has broad application prospects. With the technical performance of the application of pressure sensor in different measurement requirements has become the no pressure sensors (pressure sensor model) a an important topic of development and application. With the development of modern measurement and automation technology, the pressure sensor varieties on the market range, and the technical performance is not a lattice, lattice gauge price difference is also great. The user in front of the problem is that the pressure sensor can meet the needs of how this relates to the selection of sensors, the principle is the most economical price find the purpose, pressure range, precision, temperature range, electrical and mechanical requirements of the pressure sensor. The sensor mounted to the device after the normal operation, stable, accurate measurement. The following is the pressure sensor applied to the principle of selection in different areas. Pressure sensors are applied to different areas of selection principle 1 uses Because of different structures, relative pressure and differential pressure sensor can be divided into the determination of the absolute pressure, t
