Abstract

L'invention concerne un dispositif rotatif de détection à réponse linéaire. Elle se rapporte à un dispositif rotatif dans lequel un rotor 24 portant un aimant permanent 26 peut tourner au-dessus de deux éléments détecteurs transmettant un signal de sortie qui varie linéairement avec l'angle de rotation de l'axe du dispositif. Selon l'invention, une pièce polaire 96 est placée pres de l'aimant permanent 26 et un dispositif d'accroissement de flux 98 est placé près des éléments détecteurs. Application à la réalisation de dispositifs potentiométriques sans contact à réponse variant très peu lors des variations à température ambiante.
