Abstract
A device for determining and/or monitoring at least one process variable of a medium includes a mechanically vibratable unit, a drive/receiver unit and an electronic unit. The drive/receiver unit is designed to excite the mechanically vibratable unit to produce mechanical vibrations using an electrical excitation signal, and to receive the mechanical vibrations of the mechanically vibratable unit and convert them into an electrical reception signal. The electronics unit is designed to generate the excitation signal on the basis of the received signal, to set a frequency of the excitation signal in such a way that there is a predeterminable phase shift between the excitation signal and the received signal, and to determine the at least one process variable on the basis of the received signal, the mechanically vibratable unit comprising a diaphragm, and a surface of the diaphragm facing the process being curved.
