Abstract:
1. A method for operating an ultrasound oscillator ( 1 ) with a constant oscillation amplitude of an ultrasound oscillation system ( 1 ) including an ultrasound oscillator and components forming therewith an oscillation circuit for generating an excitation current (I), said method comprising the steps of: applying an excitation voltage (U) whose frequency is disposed outside a resonance frequency of the ultrasound oscillation system to the ultrasound oscillation system ( 1 ), adjusting the size of the excitation current (I) to a predetermined value by changing the frequency of the excitation voltage (U), detecting the level of the excitation voltage (U) and setting the predetermined value of the size of the excitation current (I) depending on the level of the excitation voltage (U).
