摘要
The invention relates to a device for continuous monitoring of the concentration of at least one gaseous component in gas mixtures. A disadvantage with known devices is, however, their complex construction, their high energy demand, their large spatial requirement and, as a result of the large mass, inhomogeneous temperature distribution, with the consequence of measurement inaccuracies, and their inertia, especially in the starting phase. The disadvantages with the prior art are avoided in the device according to the invention in that a support is designed as a lamina, on one side of which at least two electrodes are applied as mutually separated thin films, in that, on one side of the ceramic wafer, a temperature sensor separated from the electrodes is furthermore applied and in that, on the other side of the lamina, an electrical heating resistor film is provided for heating.
