Abstract

L'invention concerne le contrôle de jeux, via des capteurs (53) de déplacement capacitifs montés sur une partie fixe de partie de turbomachine à gaz et comportant individuellement des têtes de mesure (55) orientées vers des cibles d'une partie tournante se déplaçant en face d'eux. Sur la partie fixe, on rend mobiles les capteurs par rapport aux cibles, pour caler les têtes de mesure (55) en vis-à-vis des cibles.
