Remote experiments with pneumatic circuit using a double rod cylinder

This paper presents a remote operated pneumatic system for teaching purposes. The system comprises a double rod pneumatic cylinder controlled with an electrical valve, coupled with data monitoring of pneumatic pressure, limit positions, air temperature and acceleration. The system allows the remote control of the electrical valve and the operating pressure. The description of the control and data monitoring system is presented, focusing on the control architecture and user interface. A set of remote experiments implemented with the developed system are presented. Experimental results illustrate the use capabilities and its novelty training potential to explore the dynamic behaviour of a double rod pneumatic cylinder under distinct pneumatic operating pressures. Further developments centred on validated instructional design methodologies and in accreditation standards for engineering degree programs, will be considered in the future integration of this remote lab within the Moodle platform to enlarge its usability.
