Abstract:
1. A method for measuring distance between a stator ( 5 ) and an opposing rotor ( 3 ) in a machine where the stator is provided with at least one sensor device ( 7 ) of a magnetic type and configured to interact with an opposing surface on the rotor, and where a sensor body ( 10 ) is movable axially in a housing ( 11 ) mounted in the stator, comprising the steps of: receiving a signal value from the sensor device; and calibrating the sensor device by moving the sensor body in the direction towards the rotor, the size of the movement being related to the signal value from the sensor device, wherein, the movement is sufficiently large that contact is made between a first and second stop ( the first stop ( the second stop ( the second predetermined distance (e) exceeds a distance (d) between the second stop (
