| 摘要 |
The invention provides for a method for determining the relative position of at least two magnetic actuator coils (2,3,3′) in a sensor, said coils being arranged on substantially opposite sides of a sensor cartridge (1). By measuring the electromagnetic induction of one of the coils, the relative positions of the coils in the sensor device is determined. Based on the determined relative positions, these positions may be adjusted. Alternatively, the actuation currents in the magnetic coils may be adjusted based on the determined relative positions. Furthermore, a sensor device comprising a sensor cartridge, at least two magnetic coils arranged on substantially opposite sides of the sensor cartridge, and measuring means for determining the electromagnetic induction is provided.
