Abstract
SISTEMA DE SENSORIAMENTO óPTICO PARA COMBUSTìVEIS LìQUIDOS. O presente invento refere-se a um sistema de sensoriamento óptico termo-compensado para a identificação de diferentes tipos de combustíveis líquidos e/ou da proporção em misturas de combustíveis líquidos em tempo real. Nesse sistema, a fibra óptica é utilizada como guia de luz e dispositivo sensor para a determinação do índice de refração de combustíveis líquidos através do princípio da refletividade. Partindo de uma fonte luminosa, a luz é conduzida no interior da fibra óptica até a ponta de prova que está em contato com o combustível. O sinal óptico proveniente da interação entre a luz e o combustível é função dos índices de refração da fibra óptica e do combustível, do comprimento de onda da luz utilizada e da temperatura do combustível. O sistema ora proposto refere-se à utilização desse sistema óptico em combustíveis líquidos fazendo uso de fibras ópticas com índices de refração adequados em função do tipo de combustível e/ou da mistura de combustíveis em análise, possibilitando a otimização da sensibilidade do sistema óptico conforme a necessidade da aplicação. O presente invento pode ser empregado, por exemplo, em usinas de produção de álcool para o controle da concentração de água no álcool produzido e no controle de qualidade do combustível. A portabilidade do sistema viabiliza também a verificação da possível adulteração de combustíveis em todo o ciclo de produção, transporte e distribuição, através da instalação em centrais distribuidoras de combustível, caminhões, postos de combustíveis e nos próprios veículos automotivos.
