摘要
根据热释电探测器工作原理 ,对其使用特点进行了分析。在分光型红外气体分析器 (DIGA)设计原理基础上 ,建立了基于热释电探测器的红外气体分析系统输入输出数学模型。依据该模型研制了一个新型多组分红外气体分析器 ,并指出设计DIGA注意的若干问题。应用表明 ,该模型对DIGA的设计、研究。
This paper analyzes the characteristics of the pyroelectric detector based on its working principle. The input and output mathematical model of DIGA (Dispersive Infrared Gas Analyzer) system with pyroelectric detector was established according to the design principle of DIGA. We have manufactured a novel multi-gas DIGA on the basis of this model, then pointed out several problems that should be taken into account in the design. Application indicates that this model is of considerable practical value for the design, study, performance analysis and further improvement of DIGA.
