Claim 8:
9. A measuring transducer of a measuring instrument for registering a mass flow or a density of a medium flowing through at least one measuring tube of the measuring transducer, comprising:
the at least one measuring tube having an inlet and an outlet and adapted to convey the medium between inlet and outlet;
at least one oscillation exciter, which is adapted to excite the at least one measuring tube to execute oscillations;
at least two oscillation sensors, which are adapted to register deflections of oscillations of at least one measuring tube;
wherein at least one oscillation exciter as well as the oscillation sensors have, in each case, a coil apparatus with, in each case, at least one coil, as well as, in each case, a magnet apparatus,
wherein the magnet apparatus and the coil apparatus are movable relatively to one another,
wherein the magnet apparatus and the coil apparatus of an oscillation exciter, or oscillation sensor are adapted to interact by means of magnetic fields,
wherein the measuring transducer has a support body, which is adapted to hold the measuring tube,
wherein the oscillation sensors comprise, in each case, a coil apparatus,
wherein the coil apparatus includes:
at least one coil adapted for registering or producing a time varying magnetic field, wherein the coil is embodied at least sectionally using an electrically conductive trace, wherein the coil is arranged on the first face or second face of a circuit board layer,
wherein the at least one coil has, in each case, a first coil end and, in each case, a second coil end, wherein the coil apparatus has four contacting elements, wherein a first pair of contacting elements is electrically connected with a first coil end via a first connection, and wherein a second pair of contacting elements is electrically connected with a second coil end via a second connection,
wherein the circuit board has a cutting plane extending perpendicularly to the faces,

wherein the cutting plane divides the faces, in each case, into a first side and a second side,
wherein, in each case, one contacting element of a pair of contacting elements is arranged on the first side, and wherein, in each case, one contacting element of a pair of contacting elements is arranged on the second side,
wherein the coil apparatus is connectable, in each case, using at least one contacting element of the first pair and the second pair to an electronic measuring/operating circuit of the measuring instrument.
