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 bearing detection device comprises a housing body, to be fixed to a stationary ring of a bearing, and a detection arrangement on the housing body, comprising a piezoelectric transducer. The detection arrangement also comprises: a floating body, mounted on the housing body and suitable for mechanically transmitting vibrations of the bearing, and a sensor unit, which is mounted in a stationary position on the housing body and has a detection surface configured for receiving thereon a corresponding surface of the floating body. The piezoelectric transducer defines at least part of the detection surface and is configured for generating an electrical potential difference that is substantially proportional to the magnitude of a stress exerted by the floating body on the piezoelectric transducer.

摘要： A device is described wherein an actuator (3, 4; 103, 104) drives a member, such as a rack (6) meshed with a pinion (5), between two stable positions. For this purpose, elements for stopping the movable member are provided, which cooperate with elements present on the outer housing (2, 21), in which the actuator and the movable member (5, 51) are arranged, for holding at least one of said stable conditions. The device of the invention ensures low energy consumption because the actuator (3) only operates for moving the movable member from one stable position to the other.

The circuit support has, in a detection region thereof, at least one first plurality of first capacitive elements, which comprise at least one first array of first electrodes (J), preferably spaced from one another along the level-detection axis, which are arranged in a position corresponding to at least one first side of the circuit support. The sensor device has a casing body which comprises an electrically insulating and fluid-tight detection portion, which covers the detection region of the circuit support. The detection portion of the casing body comprises an overmoulded outer coating, made of a first electrically insulating polymeric material, which defines an outer surface of the casing body designed to be in contact with the medium the level of which has to be detected. The first electrodes (J) are enclosed within the supporting structure of the circuit support at least at the detection region thereof, and, at least at the detection region, between the overmoulded outer coating and the supporting structure of the circuit support there is set at least one intermediate layer made of an electrically insulating material different from the first material.
