The process in this trainer consists of
temperature control of a moving stream of air. A blower blows air into an insulated pipe.
Heater is provided to raise the temperature. Temperature sensors are provided along the
length of the tube. The heater can be controlled by a built-in amplifier. A PID Controller
is built into the equipment. The blower speed can also be adjusted. Using these, a closed
loop temperature system is established and verious types of controls such as anticipatory
, 0 error, On - Off type, etc. can be established.The open and closed loop transfer
functions and response of the process to different variable can therefore, be studied.
