一种新型红外多组份气体传感器

针对红外多组份气体分析存在的问题,采用窄带红外滤光片、光锥、热释电探测器阵列组合技术,研制了一种新型多组份气敏传感器。通过更换滤光片组件功能模块,可实现不同测量领域不同种类气体的定量分析。该传感器具有结构新颖、简单可靠、成本低等特点。实验结果表明,SO2和CO2的最大相对测量误差分别为8.3%和1.2% 。

A novel IR multicomponent gas sensor

In accordance with the problems existed in IR multicomponent gas analysis, a novel multicomponent gas-sensitive sensor is developed by using the combination of narrow-band IR filter, light cone and pyroelectric detector array. A quantitative analysis for different kinds of gas in the different fields can be carried out through changing the functional modules of filter components. The sensor has the advantages of novel structure, simple and reliable property and low costs. The experimental results show that the maximum relative measuring errors of SO2 and CO2 are 8.3% and 1.2%, respectively.
