摘要： An apparatus for ascertaining and/or monitoring a process variable, especially density of a medium. The apparatus includes: an exciting/receiving unit, which excites a mechanically oscillatable unit to execute mechanical oscillations and which receives the mechanical oscillations; an electronics unit, which applies to the exciting/receiving unit an electrical, exciter signal, and which obtains from the exciting/receiving unit an electrical, received signal. The electronics unit produces the exciter signal in such a manner, that, between the received signal and the exciter signal, a phase difference equal to a desired value of phase difference results, at which effects of changes of viscosity on mechanical oscillations of the mechanically oscillatable unit are negligible, and that the desired value of phase difference is predetermined as a function of the ratio of impedance of the exciting/receiving unit to the input impedance of the electronics unit.

摘要： A method for determining and/or monitoring a process variable of a medium, wherein a mechanically oscillatable unit is supplied with an exciter signal wherein a received signal coming from the mechanically oscillatable unit is received, and wherein the exciter signal is produced in such a manner, that a phase difference between the exciter signal and the received signal equals a predeterminable phase value. A criterion for judging the determining of the phase difference between the exciter signal and the received signal, or a signal dependent on the exciter signal or on the received signal, is established; in the case, in which the criterion for judging the determining of the phase difference is fulfilled, tuning of the phase difference is closed-loop controlled; and, in the alternative case, tuning of the phase difference is open-loop controlled. An apparatus associated with the method is also disclosed.
