基于厚膜传感器的空气质量监测仪性能及应用研究

Performance and Application Research of Air Quality Monitor Based on Thick Film Sensor

介绍了一种基于厚膜传感器技术,可同时测量NO2、O3、CO三个因子的空气质量监测仪器。深入研究了仪器的检测原理,并对仪器的质量保证及数据存储传输进行了详细介绍。最后对仪器的检测性能进行了对比分析,通过和常规点式仪器的对比表明,该仪器NO2、O3、CO三因子的检测性能能够满足实际监测要求。另外,该仪器还具有集成性好、安装调试方便等特点,因此,在道路交通监测等领域中有广泛的应用前景。

A kind of air quality monitoring instrument based on thick film sensor is introduced. Three parameters can be measured by the instrument including NO2, O3 and CO. Principle of the instrument is thoroughly researched, then quality assurance and data storage of the instrument are presented. The detecting performance is tested by the comparision with conventional instruments. The result shows that three parameters can satisfy the requirements of monitoring. Additionally, the instrument can be installed and debugged conveniently, so it can be widely used in traffic monitoring system.
