Patent ID: 8869577

Claim:
Measuring device ( 100 ) with a roll gap transmitter ( 110 ) for detecting a height (H) of a roll gap between two working rolls ( 210 - 1 , 210 - 2 ) in a roll stand ( 200 ) when the roll gap transmitter ( 110 ) is in a suitable relative position with respect to the working rolls; an initialization device ( 120 ) for detecting displacement of the work rolls in or against a rolling direction from a starting position to an end position; and a roll gap transmitter displacing device ( 130 ) for displacing the roll gap transmitter ( 110 ) in dependence on the displacement, which is detected by the initialization device ( 120 ), of the working rolls in or against the rolling direction into the relative position, which is suitable for detecting the height of the roll gap, with respect to the working rolls in the end position.
