Research of KWYJ-1 Automatic Integration System of Measurment of Gas Pressure

Traditional gas pressure calcimetre adopts pointer type pressure meter to measure gas pressure, but it only provides static data, and could not record and observe dynamic pressure data continuously. The paper introduced a digital information integration system of gas pressure by advanced computer and apparatus technology. The system can realize automation for measurement of gas pressure,and has characteristics of strong stability, high reliability and convenient maintenance. The system can be used to study the flowing rule of gas in coal bed too, which is important for us to prevent gas accident.
