Abstract:
1. A modified pressure sensor for detecting operating parameters of an electric household appliance, e.g. a washing or drying machine, provided with a relatively movable component with respect to a carcass of the electric household appliance, e.g. a tank or a basket, comprising a rigid casing accommodating a deformable membrane sensitive to hydraulic pressure, a core made of ferromagnetic material and operatively associated to the membrane for moving inside the casing in response to a deformation of the membrane, a winding fixed to the casing and operatively coupled to the core to form a variable inductance inductor; characterized in that it further comprises a mass accommodated in the casing in the immediate proximity of said membrane, free to move with respect to the casing in at least one direction corresponding to the axis of the winding and so that the inductor is adapted to emit an electric signal in response to a variation of the position of said mass induced, in use, by a variation of the position of the relatively movable component with respect to the carcass.
