Coriolis measuring transducer and coriolis measuring device

A Coriolis measuring transducer for a Coriolis measuring device for registering mass flow or density of a medium flowing through at least one measuring tube, comprising:

• the at least one measuring tube, which has an inlet and an outlet and which is adapted to convey the medium between the inlet and the outlet;
• a support body, which is adapted to hold the at least one measuring tube,
• at least one exciter, which is adapted to excite the at least one measuring tube to execute oscillations;
• at least two sensors, which are adapted to register oscillations of the at least one measuring tube;
• wherein at least one exciter and/or at least one sensor have/has, in each case, a coil device with, in each case, at least one coil, as well as, in each case, a magnet device, wherein the magnet device and the coil device are movable relative to one another,
• wherein the magnet device has a holder and at least a first magnet group having at least one magnet and at least a second magnet group having at least one magnet,
• wherein the holder has a body with a body length axis and a first end and a second end, wherein the first end has an end surface,
• wherein the body has three recesses, which extend planparallel to one another and perpendicularly to the end surface, wherein a central recess is separated from outer recesses by intermediate walls,
• wherein each intermediate wall has an opening, wherein the openings lie opposite one another across the central recess,
• wherein the coil device is arranged at least sectionally in the central recess, and wherein the first magnet group is arranged in a first opening, and wherein the second magnet group is arranged in a second opening.
