Claims (4)
1. Anordning för kalibrering av aggregatet vid en avverkningsmaskin med ultraljud, kännetecknad därav, att till anordningen hör tvä givare (1,2) som är integrerade i tvä skilda mätpunkter i aggregatet, med vilka avständet mellan aggregatets matarrullar (3,4) eller kvistknivar (5,6) frän varandra mäts genom att mäta avständet melllan mätpunkterna.
2. Anordning för kalibrering av aggregatet vid en avverkningsmaskin med ultraljud enligt skyddskravet 1, kännetecknad därav, att givarna är belägna i aggregatets matarrullarnas (3,4) eller kvistknivarnas (5,6) konstruktion.
3. Anordning for kalibrering av aggregatet vid en avverkningsmaskin med ultraljud enligt skyddskravet 1 eller 2, kännetecknad därav, att ultraljudet är modulerat med BFSK (binary freguency shift keyed)- modulering.
4. Anordning för kalibrering av aggregatet vid en avverkningsmaskin med ultraljud enligt skyddskravet 1, 2 eller 3, kännetecknad därav, att mätningen utförs genom att mäta gängtiden TOF (time of flight) för ultraljudet mellan mätpunkterna.
