A method for manufacturing a sensor element for detecting (i) a gas component in a measuring gas or (ii) a temperature of the measuring gas includes: introducing at least one functional element into at least one slip at least once in such a way that a slip layer is applied to the functional element, the functional element including at least one solid electrolyte and at least one functional layer; sintering the slip layer on the functional element; grinding the slip layer at least in the area of the at least one functional layer; impregnating the slip layer; and thermally treating the impregnated slip layer.

Sensor element for detecting at least one property of a measuring gas in a measuring gas space, containing a ground, impregnated slip layer

A gas sensor, whose purpose is to determine a physical property of a measuring gas, e.g., to determine the concentration of a gas component or the temperature of an exhaust gas. The gas sensor includes a sensor element arranged in a metal housing which is sealed by at least one sealing element arranged in a metal receptacle. The metal receptacle is affixed to the housing. The sealing element surrounds the sensor element in a centered position along its longitudinal extension L or on its half facing the measuring gas.

Gas sensor and method for production thereof

A gas sensor includes a sensor element for determining at least one physical quantity of a gas, e.g., for determining the concentration of a gas component in an exhaust gas of an internal combustion engine or the temperature of the exhaust gas. The sensor element is fixed in position by the sealing system in a housing of the gas sensor. The sealing system includes at least one sealing element, which includes a mixture of a ceramic material and a glass. The hemisphere temperature of the glass is above 750&deg; Celsius.

Sealing system for a gas sensor and a method for manufacturing the sealing system

A process for applying materials to a carrier, for which the material is atomized just prior to applying it by compressed air that is supplied separately. The process is particularly suited for the application of electrically conductive material to carriers of ceramics materials.

Process of applying material, in particular for the production of

A method for determining the adhesion of material layers of any composition on sintered ceramic elements, in particular of material layers on sensor elements for determining gas constituents in gas mixtures. The coated ceramic elements are immersed in an immersion bath consisting of a protic acid, and then subjected to a shock-type heat treatment. Adhesion is then assessed.
