The invention relates to a device for measuring and/or monitoring a process variable of a medium, comprising an oscillating unit (1), a drive/receiving unit (2) which excites the oscillating unit (1) and causes it to oscillate or which receives the vibrations thereof, an adjustment/evaluation unit (5) which adjusts the drive/receiving unit (2) or which evaluates the vibrations of the oscillating unit (1), and at least one transmission line (6) and a receiving line (7) between the adjustment/evaluation unit (5) and the drive/receiving unit (2). According to the invention, at least one third line (8) is embodied in such a way that it is disposed between the transmission line (6) and the receiving line (7) and is connected to a voltage source (9) whose output impedance is lower than the impedance of a condensate bridge.
