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.
