Abstract

L'invention concerne un dispositif pour la mesure précise de déplacements ou de déformations. Ce dispositif comprend au moins une paire de capteurs de déplacement à réactances variables 2a-3a et 2b-3b, aménagés de façon que, pour un même déplacement DELTA x, leurs réactances respectives varient de quantités égales et de signes contraires, un commutateur automatique, 10-10A, pour connecter alternativement 2a et 2b à un oscillateur électronique entretenu 8, avec une fréquence de commutation appropriée, et des moyens, 10B-12, pour former la différence des valeurs f1 et f2 sur lesquelles le commutateur 10 commute la fréquence de 8. Ce dispositif de mesure est applicable par exemple aux travaux et aux ouvrages du génie civil.
