Abstract
The washing machine comprises a support structure in which is suspended a washing chamber in which a laundry drum is mounted to be rotatable, and in which a detector is provided, capable of providing electrical signals indicating the level of the washing liquid in the chamber. The detector comprises an inductive transducer including a coil and an associated core, the relative position of which is variable according to the level of the washing liquid such that the inductance of the coil varies accordingly. The inductive transducer is coupled to the laundry drum in such a way that the inductance of the coil is variable also according to the weight of the load contained in the drum.
