Датчик и прибор для измерения магнитных параметров листовой электротехнической стали

The paper proposes new primary sensor of magnetic flux in the electrical steel sheet at her trial. This sensor is integrated with the magnetizing portion and overlaid to provide a high speed measurements of steel – up to 15 s. On the basis of the primary converter implemented device provides a measurement of the magnetic characteris-tics of the AC magnetic saturation up to the test of the sample. The device further comprises: a transducer of the magnetic field, a sinusoidal voltage with a variable frequency, variable voltage amplifier, the unit of measure-ment of electrical signals from the sensors to the personal computer interface software. The developed software allows you to set the mode of magnetization reversal, we measured the magnetic flux density of the magnetic field in the form of the dynamic of the magnetization curve and identify them on the most informative parameters of the sample: the maximum differential permeability, and a maximum magnetic induction. Distinctive feature of the device is the ability to carry out measurements on samples of arbitrary shape and size. The device is implemented on an open platform company National Instruments and can be used in the process control of production of electrical products, and for laboratory research. Application of the developed tool will allow a significant degree to increase the speed of the measurement operation while maintaining high accuracy.
