Abstract
A pressure sensor including a body, device for receiving pressure associable with a tube connected to a fluid-filled tank of an electric household appliance, wherein the level of the fluid is to be measured. It further includes a device for emitting electric frequency signal proportional to the pressure received; a device carried aboard the body, on which a plurality of response frequency values emitted by the emitting means associated with corresponding pressure values at the pressure receiving means, were recorded. The pressure sensor is used with a pressure reading system carried by the device for receiving pressure. The pressure reading system includes two devices for reading values recorded on the pressure sensor, i.e. pressure and frequency values; and electric frequency signals. The pressure reading system further includes a processing device for interpolating the pressure value associated with every signal on the basis of the values read by the reading device.
