Abstract

La présente invention concerne un dispositif de mesure de force de pression, pouvant mesurer la force de pression générée entre un premier et un second élément dans un mécanisme de pression qui génère une force de pression entre le premier et le second élément en faisant coulisser le second élément par rapport au premier élément. Le dispositif est formé de manière à ce qu'une plaque de réglage (10) soit disposée entre un premier support (2) qui supporte le premier élément et un second support (4) qui supporte le second élément. Une plaque coulissante (11) immobile par rapport à la direction de coulissement du second élément et mobile par rapport à la direction de génération de la force de pression est disposée sur la plaque de réglage (10). Des cellules de charge (9) sont disposées entre la plaque de réglage (10) et la plaque coulissante (11). La plaque coulissante (11) coulisse par rapport à la direction de coulissement du second élément lorsqu'une force de pression est générée entre la plaque de réglage (10) et la plaque coulissante (11) par le mécanisme de pression.
