Abstract: A method for making a detection device (2) for detecting a position of a movable rod (4) of a pneumatic actuator (1) comprises a step of taking a first body (17) comprising a connecting portion (19), a supporting portion (20), an electrical connector (21), a detection sensor (15) for detecting a magnetic field and electrical connecting means (22). The method then comprises a step of taking a second body (18) comprising a housing (14) in which the supporting portion (20) can be inserted, a step of inserting the supporting portion (20) and the detection sensor (15) positioned on it in the housing (14) and a step of irremovably constraining the first body (17) to the second body (18). The first body (17) and the second body (18) comprise, one at least one projecting element (25) and the other at least one corresponding hole (26); during the insertion step the projecting element (25) is inserted in the hole (26).

Abstract: A device (1) for generating a magnetic field, associable with a movable rod (3) of a pneumatic actuator (2), comprising a containment element (4) comprising an elongate portion (5) and a flange (6) at a base (7) of the elongate portion (5), a housing (8) inside the elongate portion (5), a mouth (9) of the housing (8) and a magnet (10) positioned in the housing (8), the flange (6) comprising an annular surface (11) extending mainly flat with an inner edge (12) surrounding the mouth (9) of the housing (8), characterized in that it also comprises a closing element (13) inserted in the housing (8) through the mouth (9) of the housing (8) and extending outside the housing (8) beyond a main plane of extension of the annular surface (11), and in that the closing element (13) is substantially made of an elastically compressible polymeric material solidified directly in the housing (8).

Abstract: A process for making heat exchanger tubes includes the operating steps of cutting a piece of sheet, subjecting the piece of sheet (3) to a forming step to obtain a plurality of first elements (8, 9) which mirror one another, and bending the piece of sheet (3) to create a tubular element (1) which has two flat walls (4) with the raised elements (8, 9) on them, the flat walls being opposite one another and joined by two connecting walls (5). The first raised elements (8) have an extended shape according to their main direction of extension. The forming step involves making one or more higher second raised elements (9).
