The massive spread of electro-pneumatic systems in all areas of industry has made it imperative for us to ensure reliability and the efficiency of all the components used in creating these systems, and one of the main components used is the actuator (double-acting cylinders) which can be affected by leakage problems during its life cycle due to Worn or damaged seals, this requires an ongoing air leak detection and repair program. This thesis proposes the use of "Automation Studio 7.0" for designing, simulating, and animating our system. The main objective of this thesis is to automatically test these cylinders used in our system to detect the presence of the leak and its analysis so that it can be repaired before the cylinder breaks, and this is done using the RASPBERRY PI device as our controller and CODESYS software for programming it.
