Embodiment Construction

[0035] figure 1 A magnetic circuit device 1 for a flow meter for magnetic induction is shown, the flow measuring device itself is not shown. The magnetic circuit device 1 has a coil 2. The coil 2 is made of an insulating copper wire through a turntable wrap around the coil core 3. The coil core 3 disposed in the coil 2 is flexibly designed such that the coil device consisting of the coil 2 and the coil core 3 can be curved from the first shape into the second shape. In the illustrated design, the coil core is implemented by a nickel iron alloy. The nickel ferrule is a very soft metal alloy that simplifies the curvature of the coil core 3. When selecting the material of the coil core 3, it is important that the material is not destroyed when bending, such as a break. Further, the nickel metal alloy used is highly magnetic, and is therefore particularly suitable as a material for the coil core 3.

Abstract

The invention relates to a magnetic circuit device (1) for a magnetic-inductive flowmeter, having a coil (2) that has a coil core (3). The magnetic circuit device (1) enables an increased range of application, in that it can be flexibly adapted to the geometries of the respective magnetic flow meter due to the fact that the coil core (3) is designed to be flexible in such a way that the coil (2) can be bent from a first shape into a second shape. In addition, a method (100) for manufacturing such a magnetic circuit device (1) involves the steps of provisioning, winding, heating, connecting, bending and fixing of the coil.

Description

Technical field [0001] The present invention relates to a magnetic circuit apparatus for a flow meter for magnetic induction, which is a coil and a coil core disposed in the coil. Further, the present invention relates to a coil device for a magnetic circuit device. Further, the present invention relates to a method for processing a magnetic circuit device. Background technique [0002] Various magnetic circuit devices are known from the prior art and are used to produce a homogeneous magnetic field. The magnetic field is necessary for magnetic induction flow measurements because the measurement principle is based on charge separation of charge motion in the magnetic field. [0003] The magnetic circuit device has at least one coil that generates a magnetic field. The coil core is often arranged in the coil. Most of the generated magnetic fields are directed to the pole boots through the elements guided by the magnetic field. The pole shoe is used to enable the magnetic line of t...
