The invention discloses a measurement device for measuring the rotating angle of a rotating device. The device comprises a rotating device outer flange. The outer flange and a graduated disc are coaxially fixed together. The sidewall of the graduated disc is continuously and uniformly provided with a plurality of measuring tooth surfaces arranged in the same direction. The graduated disc is externally provided with an eddy current sensor arranged towards the measuring tooth surfaces. The eddy current sensor is connected with a data acquisition unit through a signal line. The device of the invention has the advantages of simple device and strong operability. The measuring tooth surfaces are arranged at the outer circle of the graduated disc, so that the movement of a failed machine in the vertical direction has no influence on the eddy current sensor. The problem in the prior art that the conventional rotating angle measurement is not accurate is solved. The device provides important test data for reliable ope
