| Abstract: | The heating type thick film combustible gas sensing element is obtained by mixing Pt,PtO2,Pd,PdCl2 into WO3 powder and heating for 1h at stable 600 ℃.Based on the steady voltage measuring method,the relationship between the heating voltage and the sensitivity of element is researched.The experiment results show the sensitivities of WO3 combustible gase sensing element is improved 2~10 times by doping 0.5 % mass fraction Pt/Pd with the heat power at 600 mW. |
| Keywords: | gas sensing element sensitivity effect |
