Abstract
A method, system and inductive device for accurately determining inclination of a shaft arranged with a gear wheel including a plurality of gear teeth. The inductive measuring device includes a transmitter coil and at least two receiving coils arranged adjacent relative an axis of symmetry of the transmitter coil. Voltages in the receiving coils are measured, summed and integrated. A zero value for the integral is used to determine the position of the center line of the gear tooth. The invention may be used for diagnostic and/or control purposes of an internal combustion engine.
