Design of New Full-range Methane Sensor

Through improving the traditional electric bridge structure of catalytic combustion,the combination of the catalytic combustion way and the heat conduction way by using a single catalytic element is achieved,which solved the two-value problems of the traditional catalytic combustion way,on the premise of guarantee stability,the full range methane measuring is achieved.At the same time,in high concentrations of methane measurements,black component is in the low temperature preheating condition,which avoids the high concentration activation phenomenon and prolong the service life of the catalytic element.
