摘要

针对热催化瓦斯传感器特性漂移严重的问题

在对热催化瓦斯传感器灵敏度、零点时漂以及环境温度、湿度对其影响实测数据的基础上

通过最小二乘法建立了传感器特性漂移的数学模型

并提出了对其特性进行补偿的方法。实验结果表明:补偿后的瓦斯检测精度大大提高。对热催化瓦斯传感器特性漂移的机理进行了分析。

Abstract

Aimed at the serious drift problem of thermo catalysis gas sensor properties

mathematical model of sensor characteristics drift is built by least squares method on the basis of measured data of sensitivity

zero drift with time of gas catalysis sensor

and the effect of ambient temperature & humidity.The method of temperature compensation is proposed.The experimental results show that the gas detection accuracy has been greatly improved after compensation.The mechanism of thermo catalysis gas sensor characteristics drift is analyzed.
