Abstract
A sensor for detecting the level of a medium contained in a container, in particular a tank, comprises: an array of capacitive elements designed to be associated to the container (), in particular so as to extend according to an axis of detection (X) of the level of the medium (L), the array of capacitive elements comprising a plurality of electrodes (Ji-Jn), in particular on a face of an electrically insulating substrate () having a generally elongated shape, the electrodes (Ji-Jn) being spaced apart from one another, in particular along the detection axis (X), and being preferably substantially coplanar with one another; at least one insulation layer () for insulating electrically the electrodes (Ji-Jn) with respect to the inside of the container (); and a controller () having a plurality of inputs. Each capacitive element comprises at least one of a single electrode and a set of electrodes connected together in common, in particular in parallel, the single electrode or the set of electrodes being connected to a respective input of the plurality of inputs. The controller () is pre-arranged for discriminating a value of capacitance associated to each electrode (Ji-Jn) in order to deduce the level of the medium present container.
