Online Viscosity Measurement of Starch Glue for Corrugated Board Production

Working principle
The online vibration viscometer works based on the shear stress principle and measures the viscosity by the change in the vibration amplitude of a vibrating rod or vibrating plate in the fluid. Due to the viscous damping of the fluid, the amplitude of the vibration will change, and the vibration attenuation in high-viscosity fluids is faster than that in low-viscosity fluids. The energy consumed by the viscous damping of the fluid is supplemented by the circuit to maintain the vibrating element working at the resonant frequency and constant amplitude, thereby determining the viscosity of the fluid.
