Abstract
The present invention relates to a method for determining the oscillation amplitude of a sonotrode excited by a converter, wherein the converter is connected to a current generator and the current I(t) provided by the current generator and flowing through the converter is measured. According to the invention, in order to provide a method for determining the oscillation amplitude of a sonotrode excited by a converter, the voltage U(t) applied to the converter by the current generator is measured and the oscillation amplitude of the sonotorode or a field quantity of the electrical oscillation system comprising the current generator and the converter, said field quantity being related to the oscillation amplitude of the sonotrode, is calculated from the measured voltage U(t) and from the measured current I(t).
