Abstract: The cost of control system for education is getting higher and is placing extra load on the universities budgets. It is formidable to see more than five people running an experiment. The number of people joining in one experiment should be as low as possible. However, this might imply that the university/college must either have funds for buying four or five replicates of the same device or appoint more than one engineer to run the experiment. A feasible alternative is suggested in this work in which the students run the experiment through computers communicating with a PLC controlled test rig through a wireless network. A suitable number of students/computer is selected by the university. The wireless network control is for two main purposes: firstly to accept entries for various control parameters from the students and secondly to display the pressure response for them. All computers show the same display. The system includes: calibration for the sensors, the actuator, manual control part (open loop control) and automatic control (closed loop control part)
