Abstract

UN METODO Y UN APARATO PARA DETECTAR GAS PARA DETECTAR SELECTIVAMENTE UN GAS COMBUSTIBLE QUE TENGA METANO COMO COMPONENTE PRINCIPAL DEL MISMO Y UN GAS DE COMBUSTION INCOMPLETA QUE TENGA MONOXIDO DE CARBONO COMO COMPONENTE PRINCIPAL DEL MISMO. SE UTILIZA UN DETECTOR DE GAS TIPO SEMICONDUCTOR DE HILO CALIENTE Y BAJA CAPACIDAD TERMICA QUE TIENE UN SEMICONDUCTOR DE OXIDO COMPUESTO PRINCIPALMENTE DE OXIDO DE ESTAÑO DE VALENCIA CONTROLADA Y QUE ACTUA COMO UNA SECCION SENSIBLE DEL MISMO. SE MEZCLA UN OXIDO METALICO CUADRIVALENTE, RESISTENTE AL CALOR, INACTIVO A LA COMBUSTION DEL GAS EN LA SECCION SENSIBLE. SE HACE PASAR ALTERNATIVAMENTE A LA SECCION SENSIBLE DE UNA TEMPERATURA DE DETECCION DEL GAS COMBUSTIBLE A UNA TEMPERATURA DE DETECCION DEL GAS DE COMBUSTION INCOMPLETA.
