Vibronic transducer for a medium flowing through a pipe, said transducer comprising: - a measuring tube that vibrates at least temporarily during operation, particularly an essentially straight measuring tube, for conducting a medium, wherein the measuring tube communicates with the pipe via an inlet pipe segment, particularly one that is essentially straight, which leads into the inlet side and via an outlet pipe segment, particularly one that is essentially straight, which leads into the outlet side, - a counteroscillator, particularly one that is essentially straight and/or tubular, which is fixed to the measuring tube on the inlet side, forming a first coupling zone (11#) and which is fixed to the measuring tube on the outlet side, forming a second coupling zone (12#), - a sensor assembly supported at least in part on the counteroscillator, which is designed to register vibrations at least of the measuring tube, - an exciter arrangement supported at least in part on the counteroscillator, which is designed to drive at least the measuring tube, - a transducer housing which is fixed on the inlet pipe segment and the outlet pipe segment, as well as - connecting cables, particularly for the exciter arrangement and/or the sensor arrangement, wherein the connecting cables are routed at least in part along the counteroscillator on a neutral fiber that is essentially not distorted by said counteroscillator during operation and wherein the connecting cables are supported at least at points on the counteroscillator and on the transducer housing, - wherein the connecting cables are routed in an essentially symmetrical manner at least in relation to a primary axis of inertia (T1, T2, T3) of the interior part formed by the measuring tube and the counteroscillator, such that the connecting cables are routed in mirror symmetry at least in relation to one primary axis of inertia (T1, T2, T3) of the counteroscillator, namely one that is essentially perpendicular to a longitudinal axis of the measuring tube and/or the counteroscillator. - a measuring tube that vibrates at least temporarily during operation, particularly an essentially straight measuring tube, for conducting a medium, wherein the measuring tube communicates with the pipe via an inlet pipe segment, particularly one that is essentially straight, which leads into the inlet side and via an outlet pipe segment, particularly one that is essentially straight, which leads into the outlet side, - a counteroscillator, particularly one that is essentially straight and/or tubular, which is fixed to the measuring tube on the inlet side, forming a first coupling zone (11#) and which is fixed to the measuring tube on the outlet side, forming a second coupling zone (12#), - a sensor assembly supported at least in part on the counteroscillator, which is designed to register vibrations at least of the measuring tube, - an exciter arrangement supported at least in part on the counteroscillator, which is designed to drive at least the measuring tube, - a transducer housing which is fixed on the inlet pipe segment and the outlet pipe segment, as well as - connecting cables, particularly for the exciter arrangement and/or the sensor arrangement, wherein the connecting cables are routed at least in part along the counteroscillator on a neutral fiber that is essentially not distorted by said counteroscillator during operation and wherein the connecting cables are supported at least at points on the counteroscillator and on the transducer housing, - wherein the connecting cables are routed in an essentially symmetrical manner at least in relation to a primary axis of inertia (T1, T2, T3) of the interior part formed by the measuring tube and the counteroscillator, such that the connecting cables are routed in mirror symmetry at least in relation to one primary axis of inertia (T1, T2, T3) of the counteroscillator, namely one that is essentially perpendicular to a longitudinal axis of the measuring tube and/or the counteroscillator.
