The system will maintain the temperature of a process at a desired setpoint.
Another goal is to incorporate a PC-based data acquisition system (DAQ) along with LabVIEW, a graphics-based programming language by National Instruments.
LabVIEW has been used in many control systems applications .
To demonstrate the functionality of the system a heating element that gives off a constant a mount of heat was used.
The surface temperature of the heating element is regulated by varying the amount of cooling it receives. A small electric fan is placed directly in line with the heating element so that cool air is forced over it. The amount of heat transfer from the element is directly proportional to the rate of airflow over it. The system
