红外与热导双传感技术在瓦斯浓度检测中的应用研究

Gas composition is complex and harmful in mine. In order to accurately grasp the dynamic information of the gas concentration of each component, the article introduced the infrared sensor and thermal conductivity sensor gas detection principle and proposed the use of infrared sensing technology and the thermal conductivity of gas sensor technology to the concentration of gas detection, it can hold facilely real-time underground information of each component gas concentrations and improve the detection performance of gas monitoring systems helpfully.
