摘要 |
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.
