摘要： An optical sensor device (1) for a fluid substance (LS) comprises a device body (2) having a detection portion (14), associated to which is a sensitive optical part that comprises at least one of an emitter (20) and a receiver (21) of an optical radiation (Re, Rr). The detection portion (14) is made of a material transparent to the optical radiation (Re, Rr) and has an inner surface (23a, 23b) and an outer surface (15), the outer surface (15) being designed to be in contact with the fluid substance (LS) and the inner surface (23a, 23b) being designed to be isolated from the fluid substance. The at least one of the emitter (20) and the receiver (21) of the sensitive optical part is optically coupled to the inner surface (23a, 23b) of the detection portion (14), in such a way that the optical radiation (Re, Rr) is at least in part propagated through the detection portion (14), in particular with an angle and/or an intensity that is variable as a function of a characteristic of the fluid substance. The optical sensor device (1) comprises a protection arrangement, configured for preventing possible deformation of the detection portion (14) caused by an increase in volume of the fluid substance (LS), in particular deformation of at least one of its inner surface (23a, 23b) and its outer surface (15). The protection arrangement comprises at least one compensation element (13) having an elastically deformable body, which is able to contract, for compensating thereby a possible increase in volume of the fluid substance (LS) or else for enabling a reversible displacement of the detection portion (14) following upon a possible increase in volume of the fluid substance (LS).

摘要： A level sensor comprises an electrical-connection structure and a level-detection structure. The level-detection structure comprises a plurality of elongated electrodes, which include at least three measuring electrodes. The elongated electrodes extend at least partially in side-by-sidey positions in a length direction of the level-detection structure and each have a proximal end and a distal end relative to the electrical-connection structure. The level-detection structure is divided, in the length direction, into a succession of detection sections, each of which includes two effective portions of two respective measuring electrodes, the two effective portions extending to a prevalent extent substantially parallel and equidistant, at a first predetermined distance from each other, in the length direction. In the detection sections there also extends, in the length direction, a non-effective portion of one further elongated electrode other than the two measuring electrodes that define the two effective portions of the corresponding detection section, the at least one further elongated electrode being one measuring electrode or else a reference electrode. The elongated electrodes are shaped in such a way that, at one or more of the detection sections, the non-effective portion of the at least one further elongated electrode extends to a prevalent extent at respective second predetermined distances from the corresponding two effective portions, the second predetermined distances being greater than the first predetermined distance.
