/1 Frequency
control:
The ultrasound generator has an automatic search feature for resonance frequency and rate adaptation while in operation. Causes for
a change in the resonance frequency are, for example, a warming of the ultrasonic converter and the probes, a change in the acoustic
load due to changes in viscosity, and even the mounting of another probe. A frequency drift during operation is corrected by the automatic
frequency control. The optimum working frequency is sought using the resonance frequency search, e.g. after a change in probe.
/2 Power:
In the case of amplitude control, the ultrasonic power that is needed for the desired probe amplitude is dependent on the viscosity of
the medium. In order to prevent damage to the ultrasound generator and converter, the power is limited to the maximum permitted peak
value. In the case of highly-viscous media, this can also result in the desired amplitude not always being reached. The power depends
on the ultrasonic converter connected.
