Abstract

A sensor for determining an oxygen level in an exhaust gas of an internal combustion engine includes a receptacle arranged in a longitudinal bore of a metallic enclosure for a sensor element. The sensor element is accommodated in a gas-tight manner using a sensor element seal. The receptacle has a measured gas-side ceramic molded component and a connection-side ceramic molded component, which are arranged one behind the other axially. A hollow space is formed between the measured gas-side ceramic molded component and the connection-side ceramic molded component, in which a metallic sealing element is hot-pressed.
