METHOD OF MEASURING CURRENT-CARRYING CONDUCTOR SPEED Russian patent published in 2010 - IPC G01P3/50 

FIELD: measuring technology.

SUBSTANCE: invention refers to measuring technology and can be used for measuring parametres, particularly rectilinear speed of a current-carrying conductor. The method of measuring speed of the current-carrying conductor on a path segment between two identical induction sensor is based on continuous measuring excitation signals ε₁, ε₂ of two mentioned sensors with a field of the moving conductor, evaluation of informative parametre G₁ as a geometric mean value of these signals The speed v of the current-carrying conductor is determined as proportional to the mentioned informative parametre G₁. During measuring the speed, in addition signals U₁, U₂ proportional to the magnetic induction of a filed in two path points specified so that a coordinate x₀ the middle interval in-between matches with a coordinate of the middle interval between points of the mentioned induction sensors. It is combined with evaluation of the second informative parametre G₂ as an geometrical mean value of these signals and speed v of the current-carrying conductor is determined as where - a constant factor; K_B [In/tl] - sensitivity of sensors to magnetic induction; N, S_s-respectively, number of coils and the sectional area of a coil of each induction sensor; - a coefficient determined by results of preliminary physical experiment or computer modelling, thus v₀ - found experimentally or by modelling results speed of an identical or modelled current-carrying conductor in co-ordinate x₀.

EFFECT: higher measurement accuracy for speed of the current-carrying conductor.
