Abstract: A detection device for a liquid-conducting appliance includes a hydraulic body (2) defining a duct (3) for a flow of a liquid, and a flow sensor on the hydraulic body (2), which includes an electromagnetic arrangement and a detection arrangement. The detection arrangement includes two electrode units (20) for detecting a potential difference induced by the flow of the liquid through an electromagnetic field generated by the electromagnetic arrangement. The hydraulic body (2) has two through openings on two opposite sides (3a, 3b) of the duct (3), inserted in each of which is a corresponding electrode unit (20), in such a way that the electrode units (20) are opposed to one another and in contact with the liquid. The device (1) includes sealing elements at each through opening, for preventing leakage of the liquid from the duct (3).

Abstract: An optical sensor has a body including a transparent interface wall having an outer surface in contact with a liquid, to define therewith a reflection interface. An optical module is coupled at an inner surface of the interface wall, to detect a characteristic of the liquid substance via light reflection. The optical module includes a light emitter and a light receiver facing respective inclined surfaces of the interface wall. The optical module also includes a supporting structure which is elastically flexible, to enable the light emitter and the light receiver of the optical module to vary a relative position thereof and with respect to the inclined surfaces of the interface wall, when the supporting structure is secured to the inner surface of the interface wall.

Abstract: A capacitive level sensor comprises a control circuit, a supporting structure and a detection structure on the supporting structure. The detection structure comprises a plurality of electrodes, each including a connection part and a plurality of detection parts which extend in a transverse direction relative to a length direction of the sensor, the detection parts of a first electrode being interdigitated with respect to the detection parts of a second electrode. The detection structure includes a plurality of detection sections, which extend in succession in the length direction and include an upper section and one or more underlying lower sections. Each detection section includes respective first and second electrodes, which are electrically insulated from one another and with respect to the first and second electrodes of the other detection sections. The control circuit is prearranged for selectively applying an electrical potential difference between the first and second electrodes of a corresponding detection section, for detecting a value of electrical capacitance therebetween, and deriving therefrom the level of a medium.
