Abstract
Un sensore del monossido di carbonio del tipo a contatto combustione, non avente alcuna sensibilità per l'H2 il C2H5OH ed altri gas, ma che ha invece una sensibilità relativamente all'ossido di carbonio (CO) da 25 a 50 mV con una tensione al ponte da 6 a 12 V ed una concentrazione di 500 ppm.Ognuna delle bobine è fatta con un materiale a filo di un sistema di lega Fr.Pd avente un grande diametro, un valore specifico di resistenza, un certo valore di durezza Vickeres, e valori del coefficiente di temperatura i quali ricadono ciascuno all'interno di una gamma specifica. Un catalizzatore comprendente Cu2O, ZnO, MnO2, e del nero di Pt, è formato sulla superficie superiore della bobina di una parte attiva, ed un catalizzatore comprendente CuO e Cr2O3 viene formato sulla superficie superiore della bobina di una parte inattiva.
