Abstract
A method for determining and/or monitoring a process variable of a medium using a vibronic sensor includes: exciting a mechanically vibratable unit to vibrate in a first vibration mode via a drive/receiving unit using a first excitation signal; receiving and converting the vibrations of the first vibration mode into a first reception signal; generating the first excitation signal based on the first reception signal; determining the process variable from the first reception signal; exciting the vibratable unit to vibrate in a second vibration mode via the drive/receiving unit via a second excitation signal; receiving and converting the vibrations the second vibration mode into a second reception signal, where the second excitation signal is generated based on the second reception signal; and compensating for an influence of a temperature of the medium on the first reception signal using the second reception signal.
