The catalytic bead sensor is a kind of sensor which is primarily employed for combustible gas identification and detection. The catalytic bead sensor contains two fine platinum wire coils, each embedded in a bead of alumina. It is connected electrically in a Wheatstone bridge circuit. The catalytic-type bead gas sensor primarily contains two elements, viz. a detector element, which contains catalytic material and is sensitive to combustible gases, and a compensator element ...
