    摘要： A measurement sensor for determining a physical property of a measurement gas, e.g., the concentration of a gas component or the temperature of a measurement gas, in particular of the exhaust gas of internal combustion engines, has a housing and a sensor element accommodated in the housing. The sensor element has an end segment at the measurement gas side that protrudes from the housing and a connection-side end segment that bears at least one contact surface. The sensor element also has at least one conductor element that contacts the at least one contact surface. In order to achieve low transition resistances at the electrical contacting and a decoupling from mechanical stress, the contact surface and the conductor element are connected to one another by welding, and are embedded in a ceramic compound at least in the area of the welded connection.

    摘要： A gas sensor for detecting particles in a gas stream has a first electrochemical pump cell, which has a measuring chamber in which a first electrode is disposed to pump particles between the first measuring chamber and the gas stream. Furthermore, a second electrochemical pump cell is provided, which has a second measuring chamber in which a second electrode is disposed so as to pump particles. The second measuring chamber is connected to the gas stream via an absorber medium 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, and to desorb the absorbed particles in a second operating mode, and to detect the quantity of the desorbed particles. Thus, the gas sensor is able to take even low concentrations into account, and short-term measuring errors do not have such a serious effect.

    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 sealing device encloses a range of a base area and/or a cover area of a sensor element, which is accessible through an opening developed in a housing. Because of this, a seal may be achieved between the measured gas region and the reference gas region of the gas sensor, that is constructed using comparatively few individual parts, and, accordingly, also requires fewer method steps in its manufacture and assembly.
