METHOD FOR DETERMINATION OF VISCOSITY OF SUBSTANCES

摘要

Method for determination of viscosity of liquid substances that is in immersion of sensitive element arranged as probe to medium under investigation, with supply of electric current to system of excitation of vibrations of sensitive element, excitation of vibrations of probe and determination of value of viscosity of substance by change of parameters of vibration system related to value of viscosity of substance, at that one excites vibrations of probe at natural frequency, and value of viscosity of medium under investigation one determines by parameters of change of electric current at increase of amplitude of vibrations from real amplitude of vibrations when the probe is immersed to medium under investigation to amplitude of vibrations of dynamical system with sensitive element without load on the probe from medium under investigation.
