のである。This sensor (1) is formed as follows. That is, first, two plates (2) and (3) are joined by welding or the like via a cylindrical ring member (5) between them, and then the ring member (4) is joined so as to leave four bridge elements (4). Four slots (6) are machined circumferentially in the center of the ring member (6) in the vicinity of the joints of the bridge element (4) with the upper and lower plates (2) and (3). Two slots (7) are machined in to form an octagonal bridge element (4).

の貫通孔(8)が形成しである。Each bridge element (4) is all substantially identically formed and equally spaced in the circumferential direction of the plates (2) (3). Each bridge element (4) is connected to both plays (2) and (3) by only the upper and lower two sides of the octagon. Further, a circular through hole (8) is formed in the center of each bridge element (4).
