摘要： The invention relates to a method and a circuit for measuring the internal resistance (R1) (10) of an electrochemical cell (12) in order to determine the temperature of an exhaust gas sensor, especially an exhaust gas sensor of a motor vehicle. The invention aims at achieving the highest possible measuring accuracy of a circuit for measuring the internal resistance of an exhaust gas sensor with the purpose of improving regulation to constant temperatures thereby ultimately improving the performance of the exhaust gas sensor. According to the invention, a measuring current (I_Mess) (20) is impressed upon the internal resistance (R1) (10) of the electrochemical cell (12) and the resulting first voltage is detected; switchover to a reference resistance (R2) is carried out temporarily or at regular time intervals and a second voltage resulting from switchover to the reference resistance (R2) is stored and then used as reference value to measure the internal resistance (R1) (10). Switchover (18) to the reference resistance (R2) is carried out e.g. by means of force/sense lines.

摘要： For achieving a highest possible measuring accuracy of a circuit for measuring the internal resistance of an exhaust-gas sensor, a method and a circuit for measuring the internal resistance R 1 ( 10 ) of an electrochemical cell ( 12 ) are provided for determining the temperature of an exhaust-gas sensor, especially of a motor vehicle. The circuit is provided with the objective to improve the control to a constant temperature to therefore also improve the performance of the exhaust-gas sensor. A measurement current I_Mess ( 20 ) is applied to the internal resistance R 1 ( 10 ) of the electrochemical cell ( 12 ) and a resulting first voltage is detected. A switchover to a reference resistor R 2 takes place from time to time or at regular time intervals. With a switchover to the reference resistor R 2 , the resulting second voltage is stored and thereafter is applied as a reference value for the measurement of the internal resistance R 1 ( 10 ). The switchover ( 18 ) to the reference resistor R 2 takes place, for example, via force/sense lines.

摘要： The invention relates to a sensor element for determining the concentration of gas components in gaseous mixtures, especially in the exhaust gases of internal combustion engines. Said sensor element comprises at least one chamber for the gas to be measured (13) and at least one gas inlet (17) via which the gas mixture is fed to the chamber for the gas to be measured (13). The sensor element is further provided with a diffusion barrier (12) interposed between the gas inlet (17) and the chamber for the gas to be measured (13). The diffusion barrier (12) has at least one area (14, 14a, 16) that contains a catalytically active material for establishing the equilibrium in the gaseous mixture and is divided up into a coarse pored and a fine pored section.
