20080202943 | Particulate Sensor and Method For Operating a Particulate Sensor - A sensor for determining the concentration of particulates in gas mixtures is described, a soot sensor in particular, having a ceramic sensor body surrounded by a metallic housing and having a first and a second measuring electrode. In this instance, the first measuring electrode is connected to the metallic housing of the sensor or the metallic housing of the sensor is designed as the first measuring electrode. By additional electrodes on the ceramic body, the sensor is operable also as a lambda sensor. | 08-28-2008 |
20080269043 | Ceramic Insulating Material and Sensor Element Containing a Ceramic Insulating Material - A ceramic insulating material, in particular for sensor elements for determining the concentration of gas components in gas mixtures, is based on an alkaline earth-containing ceramic. The insulating material contains a hexaaluminate of the alkaline earth metal and at least one mixed compound of the alkaline earth metal with an acid oxide, the molar ratio of hexaaluminate to the sum of mixed compounds in the insulating material being 1.3 to 4.0. | 10-30-2008 |
20080271518 | Gas Sensor - A gas sensor, in particular for determining the oxygen content in exhaust gases of internal combustion engines, having a housing, a sensor element having a multi-layer design which is situated in the housing, and connecting lines lead to the outside for contacting the sensor element. A contacting element of a connecting line penetrates a layer of the sensor element and part of an insulating element situated outside the sensor element. For contacting the sensor element, such a contact configuration makes it possible to directly contact the contacting element of the connecting line, which may be arranged as a contacting pin, to the printed conductor which is formed inside the sensor element. | 11-06-2008 |
20080289961 | Sensor Element - A sensor element for determining the oxygen concentration in an exhaust gas has a conductor track applied to a solid electrolyte, which includes an electrode provided in a measuring area of the sensor element and an electrode lead connected to the electrode and situated in the lead area of the sensor element. In a transition area between the measuring area and the lead area, the conductor track has a narrowing. Furthermore, the electrode includes a first electrode section and a second electrode section, the first electrode section being connected to the electrode lead in a transition area between the measuring area and the lead area, and the first and second electrode sections being electrically connected to one another only on their sides facing away from the lead area. | 11-27-2008 |
