FIELD: measuring engineering.
SUBSTANCE: ultrasonic converter comprises the primary magnetostrictive converter of displacement in which magnetostrictive sound conductor an ultrasonic wave is excited by means of sinusoidal current and output electroacoustical converter whose frequency changes by the value of Doppler frequency when the object to be traced moves. The value of the velocity can be judged by the Doppler frequency shift.
EFFECT: improved resolution capability.
