The
ViscoScope VA-300H sensor is designed for the measurement of high viscosities.
The range which can be covered by the Model VA-300H is:
Range: 10 to 250,000 mPa.s x gr/cm3
Typically
the VA-300H sensor is calibrated for a three decade range but is capable to
cover more than 4 decades of viscosity measurement.
The
ViscoScope VA-300H sensor generates a very small torsional oscillation
resonance of constant amplitude on the probe surface. By adjusting the
amplitude, the sensor can even be configured for difficult applications. A
closed PID loop controls the amplitude of system. Viscosity is being measured
by extracting the viscosity signal from the PID control loop. Using well
established as well as new PID control technology enables a large measurement
range, long term stability and fast response.
The
entirely welded construction seals the sensor from the process. By utilizing an
extremely small amplitude of torsional resonance motion and a sealed
construction the internals of the sensor are not exposed to any wear and tear.
The
ViscoScope VA-300H sensor can be mounted in any position into a tank, reactor
or pipe. The measurement can be made, where it is most important for the
application. Current process parameters are made available for measurement and
control purposes. Turbulent flow in a tank, reactor or pipe does not have an
influence on the measurement.
