Abstract
A vibronic sensing element comprises an oscillator with a measuring tube for guiding a medium; an electrodynamic exciter arrangement; sensor arrangements for detecting the bending vibrations of the measuring tube; and a measuring and operating circuit. The exciter arrangement includes a first and a second electrodynamic exciter and a first compensation mass body. The first exciter is configured to exert a force on the measuring tube, and the second electrodynamic exciter is configured to exert a second force on the measuring tube. The measuring and operating circuit is configured to apply a first exciter signal with the eigenfrequency of a symmetric vibration mode only to the first exciter and apply a second exciter signal with the eigenfrequency of an antisymmetric vibration mode only to the second exciter.
