    摘要: Exhaust-gas sensors that have a sensor element, which is surrounded by two protective tubes on a side facing the exhaust gas and which is additionally protected by a porous fiber package, are already known. The fiber package is disposed between the two protective tubes and is meant to protect the sensor element from thermal shock by water droplets hitting the sensor element. When the exhaust gas sensor is used as primary catalytic converter or raw emission sensor, the sensor element can get damaged by sulfur compounds contained in the exhaust gas. In the exhaust-gas sensor according to the invention, damage to the sensor element by exhaust-gas components contained in the exhaust gas is reliably prevented. According to the invention, the adsorption means is implemented in such a way that sulfur, phosphorus or silicon compounds are trapped irreversibly.
