Abstract (en)
[origin: WO2008058834A1] A method for determining the temperature of a measurement sensor (10) for determining an oxygen concentration in gas mixtures, in particular in exhaust gases of internal combustion engines, wherein a detection voltage (UD) which corresponds to the oxygen concentration and is provided by a Nernst measuring cell (12) is evaluated, and the measurement sensor is regulated to an operating temperature using a heating device (50), is characterized in that the internal resistance of the Nernst measuring cell (12) is determined in a first temperature range and is used to infer the temperature of the Nernst measuring cell, and in that the internal resistance of the heating device (50) is determined in a second temperature range and is used to infer the temperature of the Nernst measuring cell.
