Abstract:
Method for, in a machine provided with a stator (5) and an opposite rotor (3), calibrating a sensor (10), arranged in the stator (5), for measuring the distance between the stator and the rotor, the sensor being of magnetic type, and zeroing of the sensor being performed by bringing the sensor (10) and the rotor (3) into contact with one another and reading the signal then obtained from the sensor during the rotation of the rotor, after which the sensor and the rotor are moved a predetermined distance apart from one another, and the signal then obtained is used as an indication of this distance, in which way the sensor signal can be used for determining the distance between the stator and the rotor, characterized in that, for zeroing and calibration, the sensor (10) is moved axially relative to the stator (5), while the axial position of the rotor (3) is kept unchanged relative to the stator (5).
