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. Displays indicate the process value and set value.
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. Specification :
