Abstract (en)
A new and useful dryer (11) has a control (35) with which sensors (22, 23) in a drum (13) of the dryer are connected via a contact path. An AC measuring signal is applied to the sensors via the contact path for determining the conductivity of wet laundry and as such the moisture of the laundry in the drum. By employing AC measuring signal, electrolyte erosion as well as passivation of contacts and sensors is avoided. <IMAGE>
