Patent 7602173 was granted and assigned to Bosch (company) on October, 2009 by the United States Patent and Trademark Office.
The invention relates to a sensor arrangement for detecting a difference angle, comprising at least one magnet field-sensitive sensor element (12), with which the magnetic field information of a magnetic circuit, consisting of a magnetic pole wheel (10) and of ferromagnetic flux rings (14, 16) with teeth (18, 20), can he evaluated. The invention is characterized in that the teeth (18, 20) extend in a radial direction for radially tapping the magnetic field information of the magnetic pole wheel (10).
