【 摘 要 】

The electromagnetic velocity sensor of Ricou and Vives with permanent magnet is well known. The probe is difficult to use at industrial conditions like metallurgy or nuclear power plants close to the Curie temperature. This article describes a reliable technique to provide controlled magnetic field distribution at the measurement area, generated by induction coils and concentrated by magnetic cores. The effect of magnetic field displacement, as well as weight and size of the assembled device, were minimized using numerical calculation of the field distribution for the case of a conducting media of different conductivity moving with different velocities. Calibration experiments showed high accuracy of measurements with low sensitivity to external electromagnetic noise.
