Zero Gauss Chamber
Zero Gauss chamber
A Zero-Gauss chamber is a cylinder closed at the ends and composed of several layers of high magnetic permeability materials (Mumetal® or Permimphy®), within which static and/or low-frequency (<1kHz) magnetic fields are extremely weak. These Zero-Gauss chambers are widely used in research and industry (e.g. Gaussmeter calibration). Attenuation factors are of the order of 1000 to 1500.
Our models
Our Zero-Gauss chambers are composed of three layers of Mumetal®, 1.0 mm thick, and an outer layer of pure iron, 2.0 mm thick. Most of the attenuation is due to the presence of Mumetal®, which has excellent magnetic permeability for medium and weak magnetic fields (earth’s magnetic field). The pure iron protects the inner layers of Mumetal® exposed to medium and strong magnetic fields.
Impact of geometry
The attenuation factor is inversely proportional to the inside diameter of the Zero-Gauss chamber. We therefore recommend selecting the smallest possible diameter for your application. The inside length should be two to three times the inside diameter to provide optimum working space. The thickness of Mumetal® is 1.0mm, but can be increased to 2.0mm for larger diameters to improve the attenuation factor.
