The present invention relates to a wrinkle detection sensor and a method for operating the wrinkle detection sensor. In accordance with the present invention, a first operating temperature is generated at the sensor for the measurement phase to allow soot to deposit on the substrate surface, while other deposits that interfere with soot measurement are prevented. To. The time from the start of measurement until the increase in conductivity between the electrodes is recorded. For the regeneration phase, a second operating temperature is generated at the sensor and the soot deposited is burned by oxygen present in the measurement gas. |
