Abstract
a. Procédé et dispositif pour mesurer la pression d'un fluide. L'invention consiste à immerger un élement solide à résonance mécanique dans un milieu soumis à une pression, à exciter la résonance dudit élément et à observer les variations de fréquence qui résultent des variations de la pression dans le fluide. c. L'invention a l'avantage d'une grande précision et finesse dans les mesures lorsqu'on utilise comme élément solide à résonance mécanique un monocristal pratiquement parfait, puisqu'elle est fondée sur les propriétés genérales ou macroscopiques de la matière constituant l'élément résonnant.
