One aspect of the invention relates to a device for measuring the blade pitch angle of a turbine engine having a first axis X, comprising:-a running wheel centered on the first axis X and provided with a plurality of blades arranged radially about the first axis X, each blade having a root, the blades are mounted at the root so as to pivot around a radial pivot second axis Y; -a fixed frame having an axis X, comprising at least one set of fixed magnetic sensors perpendicular to the first axis X; -a running wheel comprising a first magnetic target attached to the running wheel, each blade having a profile oriented along a third axis Z; -a first magnetic needle attached to the first blade and forming a first angle alpha with a third axis of the first blade, the first magnetic target serving as a marker for the first blade, the measuring device comprising a second magnetic needle attached to the second blade and forming a second angle beta with a third axis of the second blade, the first magnetic target serving as a marker for the first blade, the second angle beta is different from the first angle alpha.

    本发明的一个方面涉及一种用于测量具有第一轴线X的涡轮发动机的叶片桨距角的装置,该装置包括:‑活动轮,该活动轮以第一轴线X为中心,并设置有绕第一轴线X径向布置的多个叶片,每个叶片具有根部,叶片在根部处安装以便绕径向枢轴第二轴线Y枢转;‑具有轴线X的固定框架,该固定框架包括至少一组固定磁性传感器,该至少一组固定磁性传感器垂直于第一轴线X;‑活动轮,该活动轮包括第一磁性靶标,该磁性靶标附接到活动轮,每个叶片具有沿第三轴线Z定向的轮廓;‑第一磁性针,该第一磁性针附接到第一叶片,并与第一叶片的第三轴线形成第一角度α,第一磁性靶标用作用于第一叶片的标记,该测量装置包括第二磁性针,该第二磁性针附接到第二叶片,并与第二叶片的第三轴线形成第二角度β,第二角度β不同于第一角度α。
