Abstract
The present invention concerns a method of detecting the making or breaking of contact of a sonotrode () which is caused to vibrate with a frequency f and a vibration amplitude Awith a counterpart element (). To provide a method with which contact-making or breaking of a sonotrode with a counterpart element can be particularly quickly and inexpensively detected it is proposed according to the invention that the method has the following steps: a) recording a time configuration of the vibration amplitude A() during a first measurement time interval ΔT, and b) determining from the time configuration of the vibration amplitude A() whether making or breaking of contact occurred within the measurement time interval ΔT.
