VIBRATION VISCOSIMETER

摘要

Vibration viscosimeter that has body with viscosity indicator fixed on it, power supply block, generator of acoustic vibrations and circuit for measurement of output signal of indicator, at that it additionally has not less than two electro-vibrators arranged as coils of excitation of vibrations and fixed symmetrically in the body, not less than two slide bearings arranged as fixed symmetrically in the openings of electro-vibrators, magnetic armature arranged as placed in openings of electro-vibrators with possibility of displacement in long direction with respect to long axis of electric vibrator and the slide bearings, permanent magnet fixed at the ends of magnetic armature, induction indicators fixed on the end walls of the body, each of those is arranged as placed with gap with respect to permanent magnet, springs placed between the end of magnetic armature and the end wall of the body, at that generator of acoustic vibrations is arranged as amplifier of excitation of vibrations with low frequency.
