Universal Spindle Ranges
Example 1:
Determine the full scale viscosity range of the LV3 spindle running on an RV series
Rheometer at 45 RPM.
Spindle Speed = 45 RPM
LV Spindle Range Coefficient for RV series Rheometer = 1,280,000
Full Scale Viscosity Range = 1,280,000 = 28,444 cP (mPa•s)
45
Example 2:
Determine the full scale viscosity range of the LV3 spindle running on a 2xHA
Rheometer at 103.5 RPM.
Spindle Speed = 103.5 RPM
LV3 Spindle Range Cooefficient for 2xHA Rheometer = 2 x 2,560,000
Full Scale Viscosity Rnage = 5,120,000 = 49,468 cP (mPa•s)
103.5
Note:
The maximum viscosity taht should be taken from the DV-III+ Rheometer is at 100%
of any full scale spindle/speed range.
