| 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 |
| 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 |
| 20090189629 | SEMICONDUCTOR WAFER HAVING A MULTITUDE OF SENSOR ELEMENTS AND METHOD FOR MEASURING SENSOR ELEMENTS ON A SEMICONDUCTOR WAFER - In the measurement of sensor elements in a wafer composite, whereby non-electric stimuli are to be applied to the sensor elements, a semiconductor wafer having a multitude of sensor elements, each sensor element having a voltage supply connection, a grounded connection, and at least one sensor signal output, is configured such that a bus system is integrated in the semiconductor wafer, to which bus system at least the grounded connections of the sensor elements are connected and via which a supply voltage may be applied to the sensor elements, and that each sensor element is equipped with at least one controllable switching element for selecting the sensor element, so that only a selected sensor element supplies a sensor signal to a diagnosis device. | 07-30-2009 |
| 20090217737 | Sensor Element for Gas Sensors and Method for Operating Same - A sensor element is provided for gas sensors, in particular to determine particles in gas mixtures, the sensor element including at least one electrochemical measuring element exposed to the gas mixture to be determined, and at least one temperature-measuring element integrated into the sensor element. The temperature-measuring element includes a resistor track, which has an electric resistance of less than 180 Ohm at 0° C. The resistor track may thus be produced by thin-foil technology, such as screen printing, for example. | 09-03-2009 |
| 20100224491 | Solid-State Electrolyte Gas-Sensor Element - A gas-sensor element having a layer-type arrangement or configuration, in particular for determining gas components and/or concentrations of gas components of a measuring gas, having a sensor cell, including a first electrode, which is to be exposed to the measuring gas, a second electrode, which is to be exposed to a reference gas, and a solid-state electrolyte situated between the two electrodes, including a reference-air channel situated between the electrode that is exposed to the reference gas and the solid-state electrolyte, and including a heating element. In the superposition of two gas-sensor element layers, a path formed by an electrode facing the heating element is developed at a lateral offset with respect to a path formed by the heating element. | 09-09-2010 |
