Measurement method, sensor arrangement and measurement system |
摘要 |
In a measurement method, an array of magnetic field sensors (MS0-MS15) is provided, each emitting a sensor signal as a function of magnetic field intensity. A rotational value of a sector-wise magnetized magnetic source that is arranged movably with respect to the array is ascertained as a function of the emitted sensor signals. A set of sensor values is derived from the sensor signals. As a function of the ascertained rotational value, a number of sets of reference values is ascertained that corresponds to a number of predetermined positions of the magnetic source (MAG). The set of sensor values and the number of sets of reference values are compared to one another, and a position is selected from the number of predetermined positions as a function of the comparison.
