    • 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.
    • 具有传感器元件的废气传感器是已知的,该传感器元件被面向废气的一侧上的两个保护管包围,并且还被多孔纤维包装保护。 纤维包装设置在两个保护管之间,旨在保护传感器元件免受水滴撞击传感器元件的热冲击。 当废气传感器用作主催化转化器或原始排放传感器时,传感器元件可能被废气中所含的硫化合物损坏。 在根据本发明的废气传感器中,可靠地防止了废气中包含的排气成分对传感器元件的损坏。 根据本发明,吸附装置的实施方式是硫,磷或硅化合物被不可逆地捕获。
