Question: The temperature transmitter in an air - controller has a range of 8 to 3 0 oC through which range the pressure output changes from

The temperature transmitter in an air-controller has a range of 8 to 30oC through which range the pressure output changes from 20 to 100 kPa. If the gain of the receiver-controller is set at 2 to 1 and the spring range of the cooling-water valve the controller regulates is 28 to 55 kPa, what is the throttling range of this control?
