Abstract

Appareil servant à indiquer la valeur d'une variable et comprenant une première et une deuxième partie mobiles l'une par rapport à l'autre en fonction de ladite variable; une pluralité d'éléments d'un premier type situés sur l'une desdites parties, au moins un élément d'un deuxième type situé sur l'autre desdites parties, l'un desdits types étant magnétostrictif et l'autre étant actif afin de produire un champ à polarisation magnétique; lesdits éléments étant disposés pour que, lorsque lesdites première et deuxième parties se déplacent l'une par rapport à l'autre, des éléments différents parmi ladite pluralité d'éléments dudit premier type entrent en interaction magnétique avec au moins un desdits éléments dudit deuxième type, afin que, pour des positions différentes des deux parties, ladite interaction provoque une résonance magnétostrictive à des fréquences différentes en réponse à un champ magnétique d'interrogation alternatif auxdites fréquences différentes.
