8. Operation principle
The measurement of the diameter is performed according to the “three points”
technique, without the complete wheel coverage. The measurement method is based on
the diameter calculation by the known length of the segment chord (the distance be-
tween the ball bearings centers), which is obtained at placing the gauge onto the wheel.
The suggita of the segment is measured by means of the displacement converter. Video
