Zusammenfassung:本发明提供了一种探测头,特别是用于测定内燃机废气中的氧含量,它具有一个固定于壳体(13)内的传感元件(15),一个在壳体(13)上成形的密封法兰(25),该法兰安置于在一个废气装置(11)上构造的密封座(63)上。密封法兰(25)具有两个成形于壳体(13)上的环形件(26,27),它们各有一个倾斜面(26a,27a),其中,在壳体(13)的内部、这两个环形件(26,27)之间形成一个空腔(29)。 A sensor, particularly for determining the oxygen content in exhaust gasses of internal combustion engines, includes sensor element which is fixed in a metallic housing and a sealing flange which is integrally formed on the housing and rests on a sealing seat which is formed on an exhaust system. The sealing flange has two ring elements which are integrally formed on the housing and each have an inclined sealing surface, a hollow space being formed between the two ring elements inside the housing.
