FAQs
What viscosity range does the BEVS 1131/80 cover?
This specific model, using Spindle 2, is designed to measure materials with a dynamic viscosity ranging from (or ).
Why is Spindle 2 used instead of Spindle 1 or Spindle 3?
Spindle 2 is chosen because its geometry is optimized for the mid-range viscosity fluids. Using the correct spindle for the material’s viscosity ensures the torque reading falls within the most sensitive and accurate portion of the instrument’s measurement scale.
Does the BEVS 1131/80 measure at the same speed as the other Rotothinner models?
Yes. All BEVS 1131 Intelligent Rotothinner models are fixed-speed viscometers, operating at a constant, high-shear speed of to ensure standardized testing conditions across all available spindles.
Is the instrument suitable for non-Newtonian fluids like thixotropic paints?
Yes, the instrument is specifically designed to measure Non-Newtonian fluids. The ability to monitor the viscosity in real-time under high shear is particularly useful for characterizing the flow behavior of thixotropic materials.
How can I change the units from Poise (P) to centipoise (cP) on the display?
The instrument typically displays the results in one unit depending on the selected mode. Since the resolution is (), the results are often displayed in centipoise for finer resolution, and the conversion () is constant. The unit display can be managed through the touch screen interface.
