Patent ID: 6988424

Claim:
A method for measurement by means of a measurement arrangement ( 4 ) in which a sensor head ( 7 ) is axially movable in a sensor housing ( 6 ) and is intended, in the measurement position, to rest against a measured object ( 2 ) via an air cushion, characterized in that the inclination of the sensor head ( 7 ) in the sensor housing ( 6 ) is monitored, and in that, when the inclination of the sensor head in the sensor housing reaches a predetermined value the measurement arrangement ( 4 ) is temporarily moved a distance away from the measured object and is thereafter returned to the measurement position relative to the measured object for continued measurement, with the sensor head in the normal measuring position relative to the sensor housing, and in that the inclination of the sensor head ( 7 ) is represented by an electrical signal generated upon contact between sensor head and sensor housing.
