Abstract
A sensing wheel for a device for measuring the rotational speed and/or rotational angle of a crankshaft of an internal combustion engine has a plurality of peripherally arranged teeth, which each have a front edge and a rear edge, which define the width of the respective tooth, and tooth gaps situated between the teeth. The front edges or rear edges of each of the teeth are spaced at basically the same angular interval from one another. A limited number of different tooth widths are provided over the entire periphery, the sequence of the tooth widths of at least three successive teeth over the entire periphery being unambiguous.

A sensing wheel for a device for measuring the rotational angle of a crankshaft of an internal combustion engine comprising:
- a plurality of peripherally arranged teeth, each having a front edge and a rear edge, which define a width of the respective tooth, and
- tooth gaps situated between the teeth, respective front edges or rear edges of the teeth being spaced at basically the same angular interval from one another, said teeth having a limited number of different tooth widths provided over an entire periphery of the sensing wheel,
- wherein a sequence of the tooth widths of at least three successive teeth within a rotational angle of up to 18° over the entire periphery is unambiguous.
