VTA Pneumatic Viscosel

For Continuous Viscosity Control

Product Description

VTA Pneumatic Viscosel®

The VTA-120 includes viscosity indication and control in one complete package and is widely used on line in the printing and coatings industries for automatic addition of solvents. The Viscosel is a pneumatic viscosity indicator for inexpensive viscosity control in explosion proof environments.

Features And Benefits

Convenient & Inexpensive
Viscosity measurement and control combined in one compact package that mounts easily to process equipment on the production floor. Operating method uses the well-accepted coaxial cylinder principle of viscosity measurement.
Responsive
The Viscosel®'s sensitive response and automatic operation assures continuous conditioning of fluid.
Measures In-line
Eliminates time constraints associated with viscosity analysis of grab samples in the laboratory; provides early detection and correction of in-process deviations from desired set points.
Quality Control
Decreases raw material and product waste; maintains control of desirable product qualities (coating thickness, ink printability, % solids, etc.)
Easy to clean
Only the measuring cylinder and sample chamber come in contact with the sample. They can be easily cleaned or - if necessary - replaced without re-calibration.
Easy to Change Range
Measuring cylinders hook on and off easily, without tools and without need to adjust the instrument.
Standard or Custom Mounting
Using the standard mount, the Viscosel® can be moved wherever and whenever required. Custom bracket, cart, and tank mounts are available
1% accuracy full scale
The Viscosel® is guaranteed to be accurate within 1% of the range in use and reproducible to 0.5% of full scale range.
Easy-to-read viscosity indication
The easily read set point mark and viscosity indicator are in parallel when the instrument is on control, making possible a quick visual check, even from a distance.
Safe pneumatic operation
The Viscosel® and its drive, the indicator/controller and the valve for solvent addition are all pneumatically operated, without complex electronic circuits.
Finely modulated control
The Viscosel® system offers on/off pneumatic control with 1% throttling action. Whether working with inks, coatings or lacquers, the instrument maintains constant viscosity by controlled solvent addition. The viscometer is also available as a transducer only.
