Abstract
PARA MEDIR EL CONTENIDO, DE UN MEDIO GASEOSO, DE UN GAS COMBUSTIBLE DE NATURALEZA CONOCIDA, SE CALIENTA ELECTRICAMENTE, EN ESTE MEDIO, UN ELEMENTO RESISTIVO DE SUPERFICIE CATALITICA, O SENSIBLE A LAS VARIACIONES DE CONCENTRACION DE ESTE GAS EN ESTE MEDIO; SE DETECTA EL VALOR DE UN VALOR REPRESENTATIVO DE LA CONCENTRACION DE ESTE GAS, Y SE DEDUCE DE EL SEGUN UNA LEY DE CONVERSION OBTENIDA PREVIAMENTE POR CONTRASTE, UNA MEDICION DE ESTA CONVERSION. EL CALENTAMIENTO DE ESTE ELEMENTO SE HACE DE MANERA PERIODICA, POR CICLOS QUE COMPRENDEN UNA FASE DE CALENTAMIENTO, UNA SEGUNDA FASE DURANTE LA QUE SE REGULA LA INTENSIDAD (1) DE MANERA A MANTENER EL ELEMENTO RESISTIVO A UNA TEMPERATURA DE REFERENCIA Y SE MIDE EL VALOR ESTABILIZADO DE LA TENSION (U) EN LOS BORNES DE ESTE DETECTOR, Y UNA TERCERA FASE DURANTE LA QUE SE DISMINUYE LA POTENCIA DE CALENTAMIENTO. POR TERMINO MEDIO, LA POTENCIA DE LA CORRIENTE ELECTRICA QUE CIRCULA DURANTE ESTA SEGUNDA FASE ES SENSIBLEMENTE INFERIOR A LA POTENCIA DE LA CORRIENTE DE CALENTAMIENTO.
