Abstract

L'invention concerne les appareils de contrôle et de mesure. Le convertisseur inductif des déplacements relatifs d'objets mécaniques en signal électrique comporte, reliées à l'un desdits objets mécaniques se déplaçant relativement l'un à l'autre, des bobines primaires et secondaires associées à des noyaux et montées l'une en face de l'autre de manière à former entre elles un entrefer dans lequel est disposé un écran principal 8 relié à un autre desdits objets mécaniques, et est caractérisé en ce qu'il comprend au moins un écran supplémentaire 10 disposé dans ledit entrefer de manière à pouvoir s'y déplacer dans un plan parallèle à l'écran principal, et assurant, en coopération avec l'écran principal, l'obtention d'une fonction déterminée reliant entre eux le signal électrique et les déplacements relatifs des objets mécaniques 7, 9. L'invention peut être utilisée dans les appareils de contrôle et de mesure dont le paramètre à mesurer est converti en différents genres de déplacements.
