In the process control system, whose schematic drawing is given below; A temperature sensor is placed in the pipe to control the water temperature (T) to be fed to the advanced equipment; By means of a valve on the cold water supply pipe, the cold water flow is controlled and the temperature is kept at the set value. TC is a temperature controller; TT is a temperature transmitter. Explain what is the control strategy (FB, FF) of this process. Draw the block diagram of the process control system.
