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 (J-J), in particular on a face of an electrically insulating substrate () having a generally elongated shape, the electrodes (J-J) 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 (J-J) with respect to the inside of the container (); and a controller () having a plurality of inputs. Each capacitive element comprises a set of electrodes connected together in common, in particular in parallel, each 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 (J-J) in order to deduce the level of the medium present container.

A removable cap for fuel tanks of vehicles includes a gripping portion and a locking portion, operatively set between which is a key-operated locking device. In the closing condition of the device, a rotation movement imparted manually upon the gripping portion is not transferred to the locking portion, while in the opening condition of the device a rotation movement imparted manually upon the first part is transferred to the clamping portion. In the closing condition at least one component of the locking device is rotatable together with the gripping portion, and switching with the key of the locking device between the conditions of closing and opening causes an angular movement of the component with respect to the gripping portion, between a first pre-defined angular position and a second pre-defined angular position. The cap further includes a circuit arrangement that includes at least one sensor configured for detecting the relative angular movement between the component of the locking device and the gripping portion.
