Abstract
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.
期刊介绍：
Journal of Sensors and Sensor Systems (JSSS) is an international open-access journal dedicated to science, application, and advancement of sensors and sensors as part of measurement systems. The emphasis is on sensor principles and phenomena, measuring systems, sensor technologies, and applications. The goal of JSSS is to provide a platform for scientists and professionals in academia – as well as for developers, engineers, and users – to discuss new developments and advancements in sensors and sensor systems.
