Abstract

L'invention concerne un dispositif de mesure (1) d'au moins un paramètre d'un flux aérodynamique d'une turbomachine (50) destiné à s'étendre autour d'un axe longitudinal Z et à être baigné dans un flux aérodynamique de la turbomachine (50) et comprenant : un corps (2) s'étendant suivant un axe radial Z entre une extrémité radialement interne (4) et une extrémité radialement externe (5); et - des moyens de relevé d'informations (3) qui sont portés par le corps (2) et qui sont configurés de manière à relever des informations relatives aux paramètres du flux aérodynamique de la turbomachine (50). Selon l'invention, le corps (2) est formé de plusieurs segments de matériaux (20, 2a, 20b, 20c) différents agencés bout-à-bout suivant l'axe radial Z, le segment de matériau (20, 2a, 20b, 20c) à proximité de l'extrémité radialement interne (4) ayant une masse volumique inférieure par rapport aux autres segments de matériaux.
