Abstract

Patente de Invenção: <B>"SENSOR DE GáS"<D>. A invenção refere-se a um sensor de gás para medição de oxigênio e/ou do coeficiente proporcional de ar/combustível lambda e pelo menos um outro componente gasoso, tal como, por exemplo, hidrocarbonetos ou óxidos nítricos, em misturas de gases com um eletrodo de referência que representa uma pressão parcial de oxigênio constante, um eletrólito fixo, pelo menos dois eletrodos de medição e com linhas elétricas, para ligação e para medição para os sinais de medição elétricos. O eletrólito fixo está formado com um lado voltado para o gás de medição e com um lado de gás de referência, separado do gás de medição, sendo que a disposição dos eletrodos, com o eletrodo de referência e os pelo menos dois eletrodos de medição, fornece, simultaneamente, pelo menos dois sinais de medição baseados em princípios de medição iguais ou diferentes, aos quais servem de base componentes gasosos diferentes. Desse modo, podem ser detectados com um sensor vários componentes gasosos, o que é muito económico, particularmente para o uso como sensor de gás de escapamento ou como sensor para o comando do motor de um automóvel.
