Abstract (en)
[origin: WO02073176A2] The invention relates to a sensor for detecting gas. According to the invention, a signal evaluation (23) emits an output signal (24) whereby a predetermined weighting factor for at least two types of gas is set in the sensor element (16). A sensor heater (15) is provided and alters the temperature (Temp1, Temp2) of the sensor element (16) in a first time interval (I1) which is shorter than the time required for the sensor element (16) to create a chemical equilibrium, the sensor element (16) being at least approximately in a state of thermal equilibrium. The signal evaluation (23) evaluates the temporal sensor signal response after the temperature has been altered (Temp1, Temp2). The sensor signal (S) is at least partially located in a second time interval (I2), wherein the chemical equilibrium of the sensor element (16) is not created.
