| Abstract: | The micro methane sensor structure is proposed based on non-dispersive infrared(NDIR)spectrum absorption characterization of methane gas to avoid poisoning catalyst gas concentration detection.Infrared methane gas detection makes the signal basically without external interference,and will not produce toxic sensing head catalyst phenomenon,has advantages of high reliability and stability,which is particularly suitable for the coal mine emergency rescue and other harsh environment. |
