A catalytically active layer that is used, for example, as an electrode for a solid electrolyte-based sensor element of a gas sensor for determining a gas component in a gas mixture. The catalytically active layer includes a metallic component, that includes a noble metal in the form of platinum, rhodium, and/or palladium, and additionally a base metal. At least a portion of the originally present base metal is replaced by cavities in the metallic component.

Catalytically active layer

A sensor for determining an oxygen content in an exhaust gas of an internal combustion engine includes a receptacle, arranged in a longitudinal bore of a metal housing, for a sensing element. The sensing element is received in the receptacle in a gas-tight fashion via a sensing element seal, which includes a glass seal. The receptacle has a measured-gas-side ceramic shaped element and a connector-side ceramic shaped element, which are arranged axially one behind the other. A cavity into which the glass seal is pressed while hot is configured between the two ceramic shaped elements.

Sensor and method for the manufacture

An insulation layer of a heating device for a sensor for determination of oxygen concentration in gas mixtures, in particular exhaust gasses of an internal combustion engine, is produced by applying a silicate-free insulation base material consisting only of barium oxide and/or strontium oxide with aluminum oxide to coat the heating device ( ) and then heating the heating device with the insulation base material applied to it to temperatures of about 1350&deg; to 1600&deg; C. to form the insulation layer ( ) by sintering. The sensor includes a Nernst measuring cell provided with a first electrode ( ) and a second electrode ( ) arranged in a solid electrolyte ( ). The insulation layer ( ) is arranged between the solid electrolyte ( ) and the heating device ( ).

Method of producing an insulation layer, and sensor

A measuring sensor, in particular, for determining the oxygen content in exhaust gases of internal combustion engines, includes a ceramic molding arranged in a metal housing for the accommodation of a sensor element, in particular, planar, the sensor element being sealed by a seal element made of warm-deformable temperature-resistant material. The molded housing is designed in one piece and has a cylindrically shaped longitudinal hole on the connector side, around the sensor element, and the seal element is compressed between a first compressing element on the measuring-gas side and a second compressing element on the connector side, such that it tightly encloses the sensor element and hermetically seals the sensor element with respect to the molded housing.

Measuring sensor and method for its fabrication

A sealing member is produced from form-pressed boron nitride powder, while adding an inorganic or organic binding agent. Such boron nitride powder is obtained during the machining of boron nitride blocks composed of hexagonal boron nitride. This powder can be fractionated according to particle size and the particle size desired for manufacturing the sealing member can be separated out.

Boron nitride sealing element

A sensor for determining an oxygen content of an exhaust gas of an internal combustion engine includes a flat-plate sensing element that is inserted in a gas-tight fashion via a hybrid seal in a ceramic shaped element that is arranged in a metal housing. The seal includes a powdered sealing packing, both placed around the sensing element in a recess at one end of the ceramic shaped element and a fusible glass seal located above the powdered sealing packing. The seal achieves gas-tight and gasoline-resistant isolation or immobilization of the sensing element in the ceramic shaped element.

Seal for a sensor element of a gas sensor

An insulation layer system, in particular for gas sensors, is proposed, having at least one electrically conductive solid-electrolyte layer (10), an electrically conductive layer (20) and at least one electrically insulating layer (13) between the solid-electrolyte layer (10) and the electrically conductive layer (20). The material of the insulating layer (13) contains, prior to sintering, pentavalent metal oxides of niobium or tantalum as an additive, it being possible for the additive to diffuse into the adjoining solid-electrolyte layer (10) during sintering.
