Abstract
A sensor determines the concentration of gas components in a gas mixture with at least one measuring electrode exposed to the gas mixture and a reference electrode and with a heating device for controlling the temperature of at least one measuring electrode and the reference electrode. A measurement signal taken off the at least one measuring electrode can be changed via a corrective value, which is dependent upon the heating power of the heating device necessary to reach a pregiven value of the heating resistance of at least one heating element of the heating device.
