Videoscope-Sensor VA-300H

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.
