Abstract (en)

The method involves heating a relative humidity sensor, and measuring a reference value (FM) for a dry air at the outlet of the sensor. The heating of the sensor is stopped and drying airflow is released. A reference variation is calculated by difference of reference values for dry and humid airs. An end of the drying cycle is determined when a ratio of current variation (delta ) on reference variation attains a preset threshold value. The current variation (delta ) is measured between the reference value (FM) and a current value measured at the outlet of the relative humidity sensor. Independent claims are also included for the following: (A) a relative humidity sensor (B) a machine to dry cloth.
