Abstract
Disclosed is a measuring sensor of a measuring device for detecting a mass flow rate. The measuring sensor comprises a measuring tube, a vibration exciter, and at least two vibration sensors. The vibration exciter and the vibration sensors each have a coil apparatus having at least one coil and at least one magnetic apparatus. The coil apparatus comprises a printed circuit board having at least one printed circuit board layer, wherein the coil is formed by means of an electrically conductive conductor track, wherein the coil is arranged on the first side and/or second side of a printed circuit board layer, wherein the printed circuit board comprises at least two contact-making elements for connecting the coil to an electronic measuring and/or operating circuit of the measuring device by means of connection elements, and is characterized in that at least one contact-making element has a hole.
