Abstract: A sensor for detecting conductive particles in a gas flow, comprising a substrate having two front sides, wherein a gas flow direction is from a first front side to a second front side, wherein a resistive electrode structure comprising at least two electrodes is formed on the substrate, the at least two electrodes are electrically separated, wherein in relation to the gas flow direction, a first electrode is arranged in a first section of the sensor such that the first electrode acts as a suction electrode, wherein a sensor detection region is formed in a second section of the sensor, whereby the sensor detection region is formed by portions of the first electrode and a second electrode, wherein the second electrode is formed at least partially in a third section of the sensor.

Abstract: A sensor element with a thin-film structure is made of platinum or a platinum alloy. The structure being applied to a ceramic substrate, in particular an Al2O3 substrate and being covered by a glass-ceramic coating. The glass-ceramic coating has an outer surface with surface profiling. A sensor module, a measuring assembly, and an exhaust-gas re-circulation system include the sensor element.
