摘要： A gas sensor 10 for detecting particles in a gas stream has a first electrochemical pump cell 14, which has a measuring chamber 16 in which a first electrode 18 is disposed to pump particles between the first measuring chamber 16 and the gas stream. Furthermore, a second electrochemical pump cell 20 is provided, which has a second measuring chamber 22 in which a second electrode 24 is disposed so as to pump particles. According to the invention, the second measuring chamber 22 is connected to the gas stream via an absorber medium 34 for absorption of the particles to be detected. This makes it possible to absorb the particles to be detected in a first operating mode using the absorber medium 34, and to desorb the absorbed particles in a second operating mode, and to detect the quantity of the desorbed particles. Thus, the gas sensor 10 is able to take even low concentrations into account, and short-term measuring errors do not have such a serious effect.

摘要： A sensor element, having a ceramic body made of a laminate having at least one ceramic foil and having a heating element embedded in the ceramic body. At least the longitudinal edges of the ceramic body have a chamfer. The heat source formed by the heating element lies in the direction of the bisector of an angle which is enclosed by a chamfer's edge lying closest to the heating element. The chamfer is formed in such a way that the angle enclosed by the large surface side edge, is larger than an angle enclosed by a narrow side edge.

摘要： A sensor element for limiting-current sensors for determining the lambda value of gas mixtures, in particular of exhaust gases from internal combustion engines. The sensor element has inner and outer pump electrodes arranged on a solid electrolyte foil. The inner pump electrode is arranged in a diffusion channel that is bordered by a diffusion barrier, the pump electrode lying in the diffusion direction of the gas mixture downstream of the diffusion barrier. The gas entry hole, essentially perpendicular to the surface of the solid electrolyte foil, is led through the solid electrolyte foil into the diffusion channel. The diffusion barrier is arranged so as to be set back in the diffusion channel from the interior wall of the gas entry hole. For manufacturing the sensor element, a chamber created upstream of the diffusion barrier is filled with a cavity-creating material, which evaporates in the sintering of the sensor element and thus forms a cavity in the diffusion channel.
