GET 198–2017, State Primary Standard of Unit of Power of Magnetic Losses and Unit of Magnetic Induction of Constant Magnetic Field in Range from 0.1 to 2.5 T and Magnetic Flux from 1·10–5 to 3·10–2 Wb

Resumo

Information to improve GET 198–2011, the State Primary Standard of the unit of power of magnetic losses, is presented. A plant for reproduction of the unit of magnetic induction of a constant magnetic field in the range from 0.1 to 2.5 T and unit of magnetic flux in the range from 1·10^–5 to 3·10^–2 Wb is introduced as a standard. Studies to improve the standard were carried out in 2015–2016. The composition, operating principle, and metrological characteristics of GET 198–2017, the State Primary Standard of the unit of power of magnetic losses and unit of magnetic induction of a constant magnetic field in the range from 0.1 to 2.5 T and of magnetic flux in the range from 1·10^–5 to 3·10^–2 Wb, are described. Information on preliminary comparisons is presented.
