  • Gas sensor
    Patent number: 7445699
    Abstract: A gas sensor for detecting at least one physical magnitude of a gas, in particular of exhaust gases of an internal combustion engine, is proposed, which includes a sensor element having an electrochemical cell. The electrochemical cell includes a first solid electrolyte member on which a first electrode and a second electrode are applied. The first and the second electrode are electrically connected by means of the first solid electrolyte member. The first electrode is in contact with the gas. The area of the first electrode is smaller than the area of the second electrode.

  • Sensor element
    Publication number: 20060049049
    Abstract: A layered sensor element used in particular for detecting a physical variable of a measuring gas, preferably for detecting the temperature of the measuring gas or the concentration of a gas component of the measuring gas. The sensor element contains a heater printed conductor situated in a layer plane of the sensor element, the heater printed conductor including a heater and a heater lead and being embedded in an insulation. In the layer plane of the heater printed conductor, the insulation is surrounded by a sealing frame at least in some areas. The extension of the sealing frame in the direction parallel to a layer plane of the sensor element and perpendicular to the longitudinal axis of the sensor element at least in some areas amounts to at least 25 percent, preferably 30 percent to 80 percent, of the extension of the sensor element in this direction.
