The Zero-Gauss Shielding chamber is used for measurements that are virtually free from the influence of the earth's magnetic field and your environment.
Exclusion of the environmental magnetic field due to the Zero-Gauss chamber's high shielding factor enables accurate measurements in all directions. This is especially relevant for elongated components and for materials with a high initial magnetic permeability. Maurer Magnetics Zero-Gauss-Chamber allows for more consistent measuring results when measuring residual magnetism in ferromagnetic parts with Gauss Meters.
The Zero Gauss Chamber delivers consistent test results due to measurements taken within a chamber that shields the magnetic field of the earth. Therefore, the test results can be reproduced at any location which provides global quality control.
Measurement of residual magnetism of a milling cutter in the zero Gauss chamber. The demagnetized milling cutter has a residual magnetism of 0.1A/cm.
Measurement of residual magnetism of the same cutter in the earth's magnetic field. The induced fields falsify the measurement result from 0.1A/cm to about 2.1A/cm
Measurements of residual magnetism on ferromagnetic parts in the range of < 4 A/cm (~ 5 gauss) are typically significantly influenced by the earth’s magnetic field. Due to the geometry and permeability of the material, induced magnetic fields can be amplified several times over. Depending of the parts (e.g. 0.4 A/cm), the measurement results may fluctuate up to 4 A/cm (~ 5 gauss) at the same measuring point.
