Abstract (en)

[origin: WO02095334A1] The invention relates to a method for contactless, linear measurement, wherein a sensor line is provided with at least two magnetic field sensors (2a-c) which give off signals which respectively have a maximum value (6), a minimum value (7) and a half value (8) lying therebetween. The magnetic field sensors (2a-c) are distanced from each other in such a way that a magnetic field sensor (2a) gives off a maximum value (6) if the immediately adjacent sensor emits a signal having a half value (8). The signals of two directly adjacent magnetic field sensors are divided for evaluation and the arc tangent is formed from the result thereof.
