<p>A force transducer comprises a resilient bar (1) which carries a measuring bridge formed by resistance gages (R1, ... R4). One end of the bar is attached to a stationary support (2) and the other end is subjected to a force (P) to be measured. A method for ensuring that the signal delivered by the measuring bridge is proportional to the applied force and insensitive to parasitic couples consists in determining the initial characteristics of the transducer, in computing the relative errors arising from a displacement of the force (P) applied as a function of the angle made between the resistance gages (R1, ... R4) and the longitudinal direction (Ox) of the bar (1) and in cancelling these errors by making changes in one or a number of gages in order to modify the angle aforesaid.</p> |
