Abstract
A method for determining a load in a tumble dryer. Laundry in the tumble dryer is moved in a drum. The electrical conductivity of the laundry is determined by electrodes which touch the laundry at least from time to time resulting in a measurement signal. The electrical conductivity measurement signal exhibits pulses because of the changes in the determined conductivity of the laundry. The changes occurring during the movement of the laundry in the drum. The frequency of the pulses of the measurement signal of the conductivity is determined and serves as a measure of the load in the tumble dryer. As a result, the measure of the load is made available having a high accuracy and in a digital form. The digital form of the load is particularly advantageous for further processing in digital components.
