Abstract

Para la determinacion de la concentracion ? de oxígeno en el gas de salida de un motor de combustion interna se forma del valor medio correspondiente de la diferencia ?Vs de la tension de Nernst y la tension de referencia a partir del valor superior OW y el valor inferior UW de la tension de suma Vsum de forma rectangular y se modifica en una corriente Ip de la bomba proporcional, produce una tension proporcional ? en la resistencia Rc del calibrador; la diferencia del valor superior OW y el valor inferior UW de la tension de suma Vsum sirve como tension Vri de medicion de la temperatura para la regulacion de la temperatura de la sonda.
