Pressure Control Setup Using Pid Controller (ULP-26)

Unitech’s 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 whole system is mounted on a Table top Model with all necessary Piping. The electronic panel comprises of ADC/DAC card with RS-232 interfaces.

Software is provided for experimentation, Control action like PD, PI, PID can be conducted. Online data acquisition, trend plot are the salient feature of the system. Off line analysis, Printing of data graph can be done easily. The software is compatible with windows XP operating system. Detail Manual will be provided to conduct experiment.
