ABSTRACT:
The sensor is formed of a hollow profile (1) of rectangular cross-section, which has two symmetrical transverse notches (2, 3) and two other symmetrical transverse notches (4, 5) at a distance from the first. These notches pass through the thickness of the large side walls (6) of the profile and, in the case of each pair (2,3 and 4, 5), leave intact but mechanically weakened regions (8) between them, to which strain gauges (9) are fixed.
