Abstract

sistema de aquisição de dados para equipamento de medida da permeabilidade de meios porosos quaisquer - principalmente do solo - ao ar. patente de invenção pertencente ao campo da investigação da permeabilidade dos materiais porosos que, além de utilizar um software de aquisição de dados com uma interface amigável e passível de ser operada por qualquer usuário, ainda utiliza sensores de temperatura (com boa acurácia e com faixa de operação especificamente apropriada à medição) para monitorar as variações térmicas ocorridas durante e entre as medições, o que possibilita o cálculo da viscosidade dinâmica do ar, que é uma das propriedades envolvidas na determinação da permeabilidade intrínseca do solo e de outros meios porosos ao ar. o invento apresenta os resultados com rapidez, uma vez que o sistema automatiza a monitoração das variáveis físicas (variação de pressão, temperatura e umidade relativa de um permeâmetro) e efetua a determinação da permeabilidade do solo ao ar pelo próprio software embarcado - o qual armazena, tabula e processa os dados, exibindo-os imediatamente na forma de gráficos ou tabelas, conforme a preferência do usuário; pode ser utilizado para a determinação da permeabilidade ao ar do solo ou de outro meio poroso qualquer, e pode ser adaptado aos equipamentos de medição em uso atualmente.data acquisition system for equipment to measure the permeability of any porous media - mainly the soil - to the air. patent of invention belonging to the field of investigation of the permeability of porous materials which, in addition to using data acquisition software with a friendly interface that can be operated by any user, also uses temperature sensors (with good accuracy and with a range of operation specifically appropriate to the measurement) to monitor the thermal variations that occur during and between measurements, which enables the calculation of the dynamic viscosity of the air, which is one of the properties involved in determining the intrinsic permeability of soil and other porous media to air. the invention quickly presents the results, since the system automates the monitoring of physical variables (variation of pressure, temperature and relative humidity of a permeameter) and determines the permeability of the soil to air by the embedded software - which stores , tabulates and processes the data, displaying them immediately in the form of graphs or tables, according to the user's preference; it can be used to determine the air permeability of soil or any other porous medium, and it can be adapted to measuring equipment currently in use.
