A New Method for on-Line Measurement of Viscosity ☆

Abstract Based on the increase type rotary encoder and the cantilever elastic element, a new kind of single cylinder rotary online viscosity sensor is designed, This article mainly introduces the principle of this sensor operation and the design calculation of the elastic element. And then further this paper shows how the finite-element method of the ANSYS is used to analyze the maximum deflection and the stress of the elastic element. Finally, the measurement error of is analyzed.
