The Marimex ViscoScope process viscometer
is based on a sensor connected to a transmitter via a transmission cable.
The sensor is driven by the transmitter, which stimulates it to an oscillating torsion
at a small amplitude.
A fast closed loop PID controller
maintains the resonance frequency of the sensor at a constant level. Thus as
increases, so does the power required. This property can be used to measure the dynamic viscosity in mPa•s x gr/cm³ (η x ρ).
The inline viscometer
is ready for immediate use and responds to viscosity changes in less than 2 seconds.
The probe’s torsional oscillation
generates a shear wave with a low penetration in the liquid allowing the smallest
differences in viscosity
to be detected even under challenging process conditions.
