    摘要: A pneumatic control system, control unit and method of making the same are provided, the system comprising a pneumatic source, a pneumatically operated device that produces an output, and a control unit for interconnecting the source to the device. The control unit has an input interconnected to the source and an output interconnected to the device, the control unit having a set point for selecting a desired output of the device. The control unit has a valve unit for controlling the interconnection between the input and the output thereof so as to regulate the pressure value in the output of the control unit. The control unit has a regulating unit for operating the valve unit to tend to produce an output of the device that corresponds to the selected output of the set point. The regulating unit senses the pressure value in the output of the control unit and operates the valve unit so as to produce a pressure value in the output of the control unit that is substantially equal to the pressure value that will cause the device to produce the selected output.
