Desenvolvimento de um sistema automatizado para análise de medidas de PH

Abstract

Industrial automation has a substantial role in the development of industry, being an aggregating factor for it, reducing costs and process time. There are several industrial sectors that benefit from these resources, among which the subdivision of chemical analyzes and processes can be highlighted. This sector benefits substantially from the improvement within industrial processes that require large amounts of chemical composition data, where process automation significantly reduces production time and data analysis. One of the chemical processes that benefits from automation is pH measurement, whose present work proposes the development and construction of a robotic manipulator and a rotary table with a capacity for 28 test tubes, whose system will allow the collection of pH data from solutions automatically, as well as the digital storage of data for analysis purposes. The functionality and reliability of the system were proven through tests carried out in a controlled environment, where solutions with known pH were used, whose collection process allowed the verification of the robustness and accuracy of the mechanical system and pH measurement, whose system will benefit the UTFPR-MD's chemistry laboratory.
