The device (1) has a rotating device (2), which is assigned to signal generating regular and irregular units (3, 4), and a sensor (5) for acquiring signals. The irregular unit has a double extension related to the regular unit, which has an extension of 6 degree. The irregular unit has an extension of 12 degree, and the units are assigned respectively to two electrical signal flanks. The units are formed by teeth of a gear wheel, where the units have tops and bottoms. A plateau is arranged between the top and the bottom of the irregular unit. An independent claim is also included for a method for measuring angular speed of a rotating device comprising an angle measuring device. |
