Abstract in another language

The output of a thermoelectric gas sensor is a voltage signal that is proportional to the exothermicity, generated during oxidation of reducing gases on a catalyst. A temperature difference between the catalytically active (due to a catalyst film) and an inert part of the device is measured by screen-printed thermopiles. When the absolute sensor temperature is modulated, the resulting signals depend on the catalyst’s conversion behavior and are a characteristic for certain gas species. It could be shown that differentiation between gas components, e.g. alkanes and alkenes in a gas mixture is possible.
