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