Abstract
A coil arrangement for a flowmeter, in particular a Coriolis flowmeter or a magnetic-inductive flowmeter, having a coil, wherein the coil has a coil body and has at least one coil winding made of an electrically conductive material. The object of providing a coil arrangement that has an advantageous design in comparison to the coil arrangements known from the prior art is achieved in that the coil body is made of a ceramic material and that the coil body is produced by means of an additive manufacturing process. In addition, the invention relates to a flowmeter having a respective coil arrangement as well as a method for manufacturing such a coil arrangement.
Claims19
A coil arrangement for a flowmeter, comprising:
- a coil;
- wherein the coil has a coil body and has at least one coil winding made of an electrically conductive material;
- wherein the coil body is made of a ceramic material;
- wherein the coil body is produced by an additive manufacturing process;
- wherein the coil body is at least partially hollow in an interior bounded by coil body walls;
- wherein the material in the interior of the coil body is at least partially arranged in at least one of an irregular structure and a regular structure;
- and
- wherein the material in the interior of the coil body that is at least partially arranged in at least one of an irregular structure and a regular structure is not part of the coil body walls.
A flowmeter for determining the flow of a medium, comprising:
- a coil arrangement;
- wherein the coil arrangement has a coil, and the coil has a coil body and has at least one coil winding made of an electrically conductive material;
- wherein the coil body is made of a ceramic material and the coil body is manufactured by an additive manufacturing process;
- wherein the coil body is at least partially hollow in an interior bounded by coil body walls;
- wherein the material in the interior of the coil body is at least partially arranged in at least one of an irregular structure and a regular structure;
- and
- wherein the material in the interior of the coil body that is at least partially arranged in at least one of an irregular structure and a regular structure is not part of the coil body walls.
A method for manufacturing a coil arrangement for a flowmeter, wherein the coil arrangement includes a coil body and at least one coil winding made of an electrically conductive material, the method comprising:
- in a provisioning step, a 3D model of at least the coil body is provided;
- in a coil body printing step, the coil body is manufactured from a ceramic material by an additive manufacturing process on the basis of the 3D model;
- and
- in a winding step, the at least one coil winding is arranged around the coil body;
- or
- in a coil winding provisioning step the at least one coil winding is provided and in a coil body printing step the coil body is printed by an additive manufacturing process on the basis of the 3D model from a ceramic material at least partially in an inner region of the provided coil winding, such that the provided coil winding is arranged around the printed coil body;
- wherein in the provisioning step, a 3D model of the coil body is provided, in which the coil body is at least partially hollow in its interior;
- wherein the material in the interior of the coil body is arranged at least partially in at least one of an irregular structure and a regular structure;
- and
- wherein the material in the interior of the coil body that is at least partially arranged in at least one of an irregular structure and a regular structure is not part of the coil body walls.
