摘要

摘要用于测量各种气体成分浓度的传感器膜的温度相关特性在很大程度上影响平面气体传感器的传感器特性。因此，准确地了解这种传感器的气敏膜的温度分布是很重要的。本研究使用丝网印刷热电偶和热成像相机，展示并比较了确定保护帽内气体传感器温度分布的两种原理。数据一致性很好，未来可以使用这些结果来确定不同流量和温度条件对传感器温度分布的影响，并通过调整外围来减少这种影响，例如通过设计合适的保护帽。

Methods to investigate the temperature distribution of heated ceramic gas sensors for high-temperature applications

Abstract. The temperature-dependent properties of sensor films for measuring the concentration of various gas components affect, to a large extent, the sensor characteristics of planar gas sensors. Therefore, it is important to know the temperature distribution of the gas-sensitive films of such sensors precisely. Using screen-printed thermocouples and a thermal-imaging camera, two principles for determining the temperature profile of gas sensors inside of a protection cap are shown and compared in this study. The data agree well, and the results can be used in future to determine the influences of varying flow and temperature conditions on the temperature profile of a sensor and to reduce such effects by adapting the periphery, e.g., by designing appropriate protection caps.
