    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 sensor element is provided for determining at least one physical property of a gas mixture in at least one gas chamber, which includes at least one component to be identified, especially oxygen, and at least one oxidizable component, especially a combustion gas. The sensor element has at least one first electrode, at least one second electrode, and at least one solid electrolyte connecting the at least one first electrode and the at least one second electrode. The at least one second electrode has a lower catalytic activity, particularly a lower electrocatalytic activity with respect to the at least one oxidizable component than the at least one first electrode.

    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： The invention relates to a method for the voltage-controlled performance regulation of the heating of an exhaust-gas probe in the exhaust system of an internal combustion engine. The aim of the invention is to provide a method in which the operating temperature of the probe is achieved in the shortest possible time without damage to the probe. To achieve this, the heating voltage during the heating phase of the probe is rapidly brought up to a high temperature in a start phase in relation to a subsequent phase, or a dramatic leap in temperature is achieved, preferably up to the full operating voltage and the heating voltage is then continuously or quasi-continuously reduced.

    摘要： The invention concerns a procedure for the voltage controlled output adjustment of a sensor heater in the exhaust gas system of an internal combustion engine. In order that such a procedure, whereby the operating temperature of the sensor is achieved in the shortest amount of time, can be implemented without the sensor being damaged in the process, provision is made according to the invention, that the heating voltage in a beginning phase of the heat-up phase of the heater is brought to a high value either very quickly in respect to a subsequent phase or precipitously brought to that high value, preferably the operating voltage; and subsequently the heating voltage is continuously or virtually continuously reduced.

    摘要： A heating device for a sensor element of a gas sensor, in particular for use in exhaust gas analysis of internal combustion engines, has a heating element, which has an electrical resistor layer. The heating element is electrically insulated from at least one solid electrolyte layer by a layer containing barium and/or strontium and/or calcium. For this purpose, the heating element is embedded in a first insulator, which is adjoined by a second insulator. The first insulator has a higher barium and/or strontium and/or calcium content (expressed in weight percentage) than the second insulator.
