Automação de um processo químico de dosagem industrial supervisionado por Interface Homem-Máquina

Abstract

The use of industrial automation has increased significantly in the last decades due to the high demand by the companies to increasingly produce in less time. The automated process increases productivity, product quality, and even operator safety, as well as reducing costs for material loss and taking control and system decision-making. The chemical industry needs high precision and safety on process and for this reason has been heavily investing on their systems automation. One of the processes used in this type of industry is industrial dosing systems, which are basically a set of instruments used to handle feedstock in order to generate a product. This work deals with the development of an industrial dosing system for a chemical plant, which has robustness and precision. Because it is a self-controlled system, it is necessary to use an interface for the user to interact with it. The weight reading is performed using the Modbus RTU industrial network in order to guarantee accuracy in measurement.
