Abstract in another language

High-temperature gas sensors need homogeneous heating in the functional sensing area. Varying gas flow characteristics lead to cross-effects and signal instability. Utilizing a special sensor transducer, these effects can be proven experimentally. FEM modelling further supports the understanding. Proper protection caps solve cross-sensitivity problems but also cause decreasing sensor response.
