A pneumatic control system is a control system consists of
pneumatic instruments.i.e,pneumatic transmitters,pneumatic
controlers,pneumatic actuators,pneumatic final control
elements etc.These instruments are working basically with
pneumatic signals(air pressure signals).Unlike an
electronic control system,which works on elecric signals
(voltage,current etc),a pneumatic controls system utilizes
air pressure signals for the communication.Tubes are used
for the transmission of these signals like wires and cables
in an electronic control system.
