Piston pressure gauge is one of the most sophisticated measuring instruments in pressure measurement technology occupies a very important position, it is to assess or test industrial and agricultural production, scientific research, national defense construction in all aspects of the use of various types of pressure equipment, whether the instrument Qualified standard, widely used in scientific research and measurement of pressure requirements of certain production processes with high accuracy. The pressure value is an indispensable important control parameter in the production automation. The pressure instruments used in the production process and the measuring result of the instrument are accurate or not, which will directly affect the economic benefit and the energy utilization rate of the enterprise.
