Abstract

EL SENSOR DE GAS MUESTRA UN SISTEMA DEPENDIENTE DE LA TEMPERATURA Y DEL GAS Y OTRO SISTEMA PROXIMO A EL DEPENDIENTE SOLO DE LA TEMPERATURA. MEDIANTE LA DETERMINACION DE LAS DIFERENCIAS ENTRE LAS SEÑALES DE SALIDAS A PARTIR DE LOS DOS SISTEMAS O DE LA RELACION DE SEÑALES RESPECTIVAS, ES POSIBLE OBTENER UN VALOR DE MEDICION QUE ES INDEPENDIENTE DE LAS FLUCTUACIONES DE TEMPERATURA Y DE FORMA CORRESPONDIENTE MAS SENSIBLE AL GAS.
