ABSTRACT:
A engine exhaust gas measuring sensor having a sealing device and having a sleeve suitable for connection to a housing including a sealing element which is arranged at an end of sleeve facing away from the housing so that a reference air chamber is formed within the sleeve. The sealing element also has at least one opening extending longitudinally and at least one oblong contact which penetrates the opening and serves the purpose of establishing an electrical bond with a sensor element of the lambda probe. A glass seal is placed within the opening for the purpose of sealing and insulation. The glass seal encloses a longitudinal section of the contact located within the opening in the form of a jacket. The sealing element and the sleeve are made of metal. A method for making such an engine exhaust gas sensor includes the steps of introducing solder glass in a sealing element opening, heating the solder glass so that it becomes fluid and cooling the glass so that is solidifies or sets.
