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 lambada e óxido nítrico em misturas de gases. Para medir confiavelmente vários componentes gasosos, o sensor está dotado de um eletrodo de referência, que representa uma pressão parcial de oxigênio constante, com pelo menos dois pares de eletrodos, sendo que a dois pares de eletrodos está respectivamente associado um eletrodo comum, com eletrólitos fixos, dispostos entre os dois eletrodos de uma par de eletrodos, diretamente nos eletrodos, sendo que o eletrólito fixo entre um primeiro par de eletrodos é permeável a gás e o eletrólito entre um segundo par de eletrodos é estanque a gás, sendo que o segundo par de eletrodos está previsto para a medição potenciométrica ou amperométrica da concentração de óxido nítrico, sendo que o primeiro par de eletrodos está formado para aplicação de uma corrente ou de uma tensão, para bombeamento de oxigênio e sendo que o eletrodo comum forma o catódio do primeiro par de eletrodo e o segundo eletrodo do segundo par de eltrodos está formado como eletrodo de referência no lado do gás de referência do eletrólito fixo do segundo par de eletrodos, e sendo que, além disso, estão previstas linhas elétricas para ligação e para medição para os sinais de medição elétricos.
