Abstract

A method for operating a thermal conductivity sensor includes the following steps: (i) applying a supply voltage to a measurement element of the thermal conductivity sensor, wherein the supply voltage results in a temperature increase of the measurement element to a characteristic temperature at which the measurement element is sensitive to a thermal conductivity of an analysis gas, (ii) performing a first measurement by the measurement element during the temperature increase before the measurement element has reached the characteristic temperature, thereby providing a first measurement value, (iii) performing a second measurement by the measurement element at a time when the measurement element has reached the characteristic temperature, thereby providing a second measurement value, and (iv) obtaining a compensated measurement value by compensating an offset of the second measurement value based on the first measurement value.
