摘要
在煤矿瓦斯抽放系统中,管道环境压力变化范围一般达40～ 120 kPa.环境压力的变化,会造成电化学气体传感器检测异常.以电化学一氧化碳传感器为例,用实验手段建立环境压力影响的补偿数学模型和求解.实验验证该方法对一氧化碳压力影响效果显著,能够扩大电化学气体传感器的应用范围.
Abstract ： In the coal mine methane pumping system, the changing range of pressure in pipe is generally from 40 to 120 kPa. The change of environment pressure will cause the detecting abnormity of electrochemical gas sensor. Takes CO sensor for example, using experimental method builds and solves mathematics model with the offset of environment pressure. The experiment verifies that this method is valid for CO pressure influence, and spreads application scope of electrochemical gas sensor.
