Abstract
The present disclosure relates to a measuring transducer of a measurement device for registering a mass flow or a density of a medium The measuring transducer includes a measuring tube, at least one exciter adapted to excite the measuring tube to execute oscillations, and two sensors adapted to register deflection of oscillations of the measuring tube. The exciter and the sensors each have a coil device including a circuit board with a first coefficient of thermal expansion. The coil device of the sensors or exciter are/is secured using a holder apparatus adapted to clamp the circuit board, wherein the circuit board is mechanically contacted by the holder apparatus using at least one holder element, wherein the holder element has a second coefficient of thermal expansion, wherein the first coefficient of thermal expansion and the second coefficient of thermal expansion differ from one another by less than 3*10−6/Kelvin.
