摘要: A sensor for determining a physical property such as the concentration of a gas component or the temperature of a measuring gas, e.g., the exhaust gas of internal combustion engines, has a sensor element which is secured in a housing and is surrounded at an end section on the measuring gas side by a protective tube and surrounded at an end section on the connection side by a protective sleeve, and also has a radially projecting flange for securing the sensor on a sealing seat formed on a measuring gas duct. To reduce manufacturing costs, the flange is molded onto the protective tube as one piece. The protective tube is manufactured as a deep-drawn part, and a trimming edge remaining after deep drawing on the end side is used as a securing flange.

摘要: A gas sensor, in particular for determining the content of gases in the exhaust of an internal combustion engine, has a contact part carrier composed of two opposing, externally symmetrical half-shells, engaging in and contacting the terminal end of a sensor which runs axially and is installed in a tubular protective sleeve, with the half-shells of the contact part carrier being held together by a spring element. The spring element is designed to exert only a low clamping force on the half-shells of the contact part carrier in a first bracing step when the contact part carrier is pre-mounted on the terminal end of the sensor, so that the sensor can still be inserted easily between the two half-shells. In a second bracing step it presses from all sides against the two half-shells due to the inside wall of the protective sleeve and pushes them against the supporting contact points with a greater force than in the first bracing step.

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 sensor device, particularly for determining the oxygen content in exhaust gases of internal combustion engines, having a sensor element that is surrounded gas-tight by a seal and fixed in a housing. The seal (19) is inserted as a pre-sintered, deformable sealing body (19') into the housing (12), between a ceramic molded body on the side of the measured gas and a ceramic molded body on the connection side (18, 20); the pre-sintered sealing body (19') can be deformed under pressure. The ceramic molded parts (18, 20) and the sealing body (19') have respective axially-extending throughgoing holes (32, 42, 52). The sealing body (19') has formed-on structures that narrow the cross section of the throughgoing hole (42) and are deformed by the sensor element (22) when the sensor element (22) is inserted such that the sensor element (22) is stopped, arrested or fixed in the installed position in the throughgoing hole (42) by the formed-on structures. The facing end faces of the ceramic molded parts (18, 20) and of the sealing body (19') each have form-fitting engaging elements that engage one another and rest against the opposite, touching end faces, which engaging elements orient the ceramic molded parts (18, 20) and the sealing body (19') radially such that the respective throughgoing holes (32, 42, 52) extend in alignment with one another.
