The ViscoScope process viscometer consists of a sensor connected to a transmitter via a transmission cable.
The transmitter drives the sensor stimulating it to an oscillating torsion at a small amplitude. A fast closed loop PID controller keeps the resonance frequency of the sensor constant. Thus the higher the viscosity, the greater the power required. This can be used to measure of the dynamic viscosity in mPa•s x gr/cm³ (η x ρ). The inline viscometer is ready to perform measurements immediately and reacts to changes in viscosity in less than 2 seconds.
The torsional oscillation of the probe generates a shear wave with a low penetration in the liquid. This technology makes it possible to detect the smallest differences in viscosity even under challenging process conditions.
