Adtron Model 4021C, Pressure Control Setup comprises of Pressure tank fitted with pressure transmitter to measure the Pressure. The pressure is controlled by a pneumatic control valve operated by a I to P converter. The Input pressure is fed from air compressor. The whole system is mounted on a Table top Model with all necessary Piping. The electronic panel comprises of ADC/DAC card with RS – 232 interface. Software is provided for experimentation, PID Control settings ( P, PI, PD and PID mode ) Data storing, Online data acquisition, Off line analysis, Printing of data’s can be done easily.
