Design of Detecting System of Air-Tight Tester Based on PLC
Abstract：Describes the detecting system of an air-tight tester, which detects the pressure m me mgn-pressure vessel real-timely. Siemens S7-200 PLC is adopted in the system as the main monitoring element. The monitoring screen is formed by force controlling configuration software. The parameters of system may be settled and the operation may be displayed. The working channel is selected according to the needful level of pressure. The multichannels of detecting system may work simultaneously. The site tests show that the design of the system is correct and reliable.
