Abstract
The present disclosure relates to a method for determining a process variable of a medium by means of a vibronic sensor. In a first operating mode, an oscillatable unit is excited by a first electrical excitation signal, such that it executes mechanical oscillations, and the mechanical oscillations of the mechanically oscillatable unit are received and converted into a first electrical, received signal having a first frequency. Furthermore, the first received signal is evaluated relative to the process variable. In a second operating mode, mechanical oscillations of the oscillatable unit are received and converted into a second electrical, received signal, wherein a second frequency of the second electrical, received signal is ascertained, and wherein the second frequency is associated with a first disturbing influence for the vibronic sensor. Furthermore, the present disclosure relates to an apparatus, which is suitable for performing a method of the present disclosure.
