Abstract

L'invention concerne les dispositifs de mesure électriques. Le dispositif faisant l'objet de l'invention est caractérisé notamment en ce que chacun des circuits de régulation de tension se présente sous forme d'un compensateur principal, les transducteurs de la grandeur à mesurer 2, 3, divisés en deux groupes égaux, étant insérés dans le pont de mesure par l'intermédiaire des compensateurs principaux et de deux compensateurs supplémentaires 8 à 11. L'invention peut être utilisée dans toutes les branches de l'industrie pour effectuer des mesures en plusieurs points à l'aide de transducteur tels que par exemple des extensomètres ou des thermomètres à résistance.
