Design and construction of pressure leak testers through the analysis of the filling level for the detection of defects in the nozzle of plastic containers

Plastic Container Manufacturing Process, many equipment has been developed for the detection of defects, for example: vision cameras, pressure test leak testers, colorimeters, hermeticity cameras, etc. each form is designed to detect a specific defect, it is updated as technology improves. Currently, the industry has opted for the use of microcontrollers that help automate industrial processes, one of the most used micros is Arduino due to its simplicity of programming and low cost of operation. The objective of this work is to apply an Arduino system for the monitoring of pressure leak testers in plastic containers. Finally, the paper shows the possible change of a particular system based on PLC with ladder logic language, by a simple system based on microcontrollers.
