Abstract
A vibronic measuring device for determining at least one process variable of a medium. Included are: an oscillatable unit; a transmitting/receiving unit, which, by means of a transmission signal, excites the oscillatable unit to execute mechanical oscillations and receives the mechanical oscillations and converts such into an analog, electrical, received signal; and a control/evaluation unit (MC), which receives the analog, received signal, digitizes such and determines the process variable therefrom and which produces the transmission signal. Between the transmitting/receiving unit and the control/evaluation unit, a controllable amplifier is arranged, which receives the received signal and produces an adapted, received signal, and that the control/evaluation unit determines an amplitude of the received signal and, as a function of the determined amplitude, controls the amplifier in such a manner that the amplitude of the adapted, received signal is adapted to a digitizable voltage range predetermined by the control/evaluation unit.
