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&#xb0; C. The resistor track may thus be produced by thin-foil technology, such as screen printing, for example.

Sensor element for gas sensors and method for operating same

A gas sensor is for determining at least one physical quantity of a gas, e.g., an exhaust gas of an internal combustion engine, the gas sensor having a sensor element that is fixed in a housing of the gas sensor by a seal assembly. The seal assembly includes a sealing element, which has a ceramic and/or a metallic material. After the heat treatment, the sealing element has a maximum decrease in volume of 5 percent, or an increase in volume, based on the volume of the sealing element prior to the heat treatment.

Gas sensor

A sensor element for gas sensors for determining the concentration of particulates in gas mixtures, in particular soot sensors having at least one first measuring electrode applied to an electrically insulating substrate and at least one second measuring electrode, a voltage being applicable to the first and second measuring electrodes. The first measuring electrode is at least partly covered by a porous material open to diffusion of the particles to be determined.

Sensor element for particle sensors and method for operating the sensor element

A sensor for determining the concentration of particles in gases, in particular of soot particles, has at least one substrate element, and a measuring area between at least one first and one second measuring electrode, the two measuring electrodes being configured so that by applying a voltage between the measuring electrodes, an asymmetric electric field is formed on the measuring area. The sides of the first and second measuring electrodes, facing one another, may not be parallel to one another, for example. Furthermore, at least one measuring electrode may have a structure along the side facing the other measuring electrode or along the finger electrodes.
