Classification: CPC G  H | IPC G  H

Claim 0:
1. A coil apparatus of an oscillation sensor or oscillation exciter of a measuring transducer or a measuring instrument for measuring a density or a mass flow of a medium flowing through at least one measuring tube of the measuring transducer, or measuring instrument, comprising:
a circuit board having at least one circuit board layer, wherein each circuit board layer has a first face and a second face plane parallel to the first face,
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.
