The centre of collective usage of scientific instruments

"Complex for measurement of magnetic parameters of technical objects"

The centre of collective usage of scientific instruments (CCUSI) "Complex for measurement of magnetic parameters of technical objects" is created at SI «ITPM of NASU» in 2008 within the framework of the Program of the centralized acquisition of scientific instruments and installation form the budget costs of NAS of Ukraine with the purpose of the most rational usage of the unique scientific means.

The basis of CCUSI is the Magneto-dynamic complex of the SI «ITPM of NASU», which is located in the east part of Kharkov, occupies territory of 5,3 hectares and includes the magnetomeasuring stand by the total area of 450 sq. m, machine hall with power equipment, laboratorial and subsidiary facilities. The magneto-measuring stand of the Complex is constructed under the special project using the building, engineering and technological constructions made from only non-magnetic materials, which allows to reduce the level of magnetic interferences up to a thousandth part of a percent of the Earth’s magnetic field; the Stand is located in a spatial zone of "magnetic silence" - technological ground area, free from sources of magnetic interferences.

Now the Magneto-dynamic complex is equipped with magnetomeasuring apparatus for measurement of magneto-static fields in the diapason 1•10-9 ÷ 1,5 Ò and AC low-frequency magnetic fields in the diapason 1•10 -9 ÷ 1•10 -4 Ò.

  • sensors of magnetic field, computer and power supply of the scientific instrument;
  • the amount of sensors - 6;
  • continuous measurement and recording of current magnetic field values;
  • reading of the measured values directly on the monitor;
  • indication of the measured values on the monitor in graphic and tabular forms;
  • saving the measured values in different formats;
  • highest possible distance from sensors to a computer is 25 m;
  • operation from external AC power supply.

Facilities of the scientific instrument allow to carry out works in the following directions:

  • investigation of spatial structure of magnetostatic fields;
  • measurement of dipole magnetic moment;
  • determination of spatial harmonics of the magnetic moment;
  • investigations of magneto-static field created by technical objects.
