摘要： An electrochemical sensor for determining the oxygen content of gases of internal combustion engines includes a ceramic element that is inserted with a sealing ring into a housing. The sealing ring is built up from different metal layers. The arrangement of the metal layers proceeds from a metal support which is composed of a steel alloy. The sealing ring is covered on both sides with a roll-clad copper layer. A nickel layer can additionally be arranged beneath the copper layer.

摘要： 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.

摘要： A Lambda probe type gas sensor for use in determining the oxygen content of exhaust gases produced by an internal combustion engine includes a sensor element of the electrochemical, solid electrolyte, metallic oxide semiconductor or Lambda air-fuel ratio variety, which sensor element is arranged in a metallic housing and is contacted by connecting cables that are brought out of the metallic housing. These connecting cables are each surrounded by cable insulation that is made of PTFE (Polytetra-fluoroethylene). The surface of the cable insulation has, at least in certain areas, a gas-permeable section that allows a reference atmosphere to arrive inside the cable insulation and, from there, in the metallic housing. The gas-permeable section, on the other hand, prevents ingress of liquids such as fuel, condensed water, etc., This is achieved, for example, by an additionally applied, PTFE film that is placed over the gas-permeable section.

摘要： A seal for a sensor element of a gas sensor for determining the oxygen content in gases including exhaust gases of an internal combustion engine, which seal seals the sensor element in a longitudinal bore of a housing, the seal including a sealing stack which is positioned within the longitudinal bore of the housing and around the sensor element in use and which is comprised of two sealing bodies and an additional seal positioned between the two sealing bodies. The two sealing bodies are comprised of a pre-sintered ceramic material. The additional seal is comprised of a pre-pressed powder material and has a porosity which is lower than that of the two sealing bodies. The two sealing bodies and the additional seal are compressed together within the longitudinal bore in use, whereby at least the additional seal is deformed so that the sensor element is sealed in a gap-free manner within the longitudinal bore. The pre-pressed powder material of the additional seal may consist essentially of a ductile metal, which may be one of nickel or copper, or graphite which may be fiber-reinforced.
