Abstract

The invention relates to a force inducer (10) for measuring tractive and/or compressive forces, comprising a tab-type body (12) which absorbs the force to be measured in such a way that the force triggers an elastic deformation of the body (12) or a positive or negative expansion in at least part of the body (12). Said force inducer also comprises at least one electrical measuring system (29) which is coupled to the body (12) and detects the deformation or the expansion and converts it into an electrical signal. The body (12) is longer in the longitudinal direction (14; X) than in the transversal direction (Y) and in the vertical direction (Z), and comprises a central opening (26) for receiving the electrical measuring system (29). The central opening (26) of the body (12) is continuous in the vertical direction (Z) and crossed by a plate (28) which can be connected to the electrical measuring system (29).
