Abstract: A method for manufacturing a catalytic combustible gas sensor is provided to increase sensitivity of the catalytic combustible gas sensor by causing an oxidation of relatively inflammable gas easily. A method for manufacturing a catalytic combustible gas sensor includes the steps of: preparing a mixture by mixing 65-75wt% of Al2O3 powder with 25-35wt% of titania nanotube powder in which platinum and palladium are dispersed; applying the mixture onto a platinum heater formed on an alumina substrate(3) to form a sensing device(6), and applying Al2O3 powder onto a separate platinum heater to form a compensation device(5); and fixing each of the alumina substrates having the compensation device and sensing device to catalytic combustible gas sensor support rods(2) using a spot welding machine and platinum wire(4). Further, the mixture is made by mixing 70wt% of Al2O3 powder with 30wt% of titania nanotube powder.

Abstract: A catalytic combustion type flammable gas sensor using a UV LED and UV-catalyst is provided to obtain good flammable gas detection performance at a low voltage. A catalytic combustion type flammable gas sensor using a UV LED and UV-catalyst includes an alumina substrate(3), a platinum heater, a detection device(6), a compensation device, an LED(7), and a body(1). The platinum heater is formed on the alumina substrate. The detection device is formed by printing a mixture on the platinum heater, where the mixture comprises Al2O3 powder 70 to 80wt%, nano particles TiO2, photocatalyst 3 to 7wt%, and PdCl2 8 to 12wt%. The compensation device is formed by screen printing Al2O3 powder on the platinum heater. The LED is fixed to the body to emit ultraviolet rays to the detection device.
