Temperature Control Setup 4021A

Categories: Control Engineering

4021A                      Adtron Model 4021A Temperature Control Loop Setup comprises of RTD temperature sensor to sense the temperature. The water flows through the Rotameter and Process tank to which a heating coil is fitted. The heater is controlled by a Thyristor drive. The Thyristor drive is connected to PID controller. The manual control valve can control the water flow. The system is mounted on a tabletop model with all necessary piping. The water inlet and outlet are brought out through a manual control valve. Water at approx. 100 LPH has to be supplied to the system externally. 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.
