Abstract

a. Dispositif de mesure de contrainte utilisant un pont de Wheatstone. b. On fait en sorte que la tension de la source de courant du pont soit variable et ces tensions différentes sont appliquées au cours de deux mesures successives au montage en pont. Les tensions déséquilibrées obtenues sont mises en mémoire et soustraites les unes des autres, ce qui permet d'obtenir une valeur mesurée précise de la contrainte qui n'est pas affectée par la tension de dérive ou par la force électromotrice thermique. c. Applications : jauges de contrainte.
