VAN-SP-1
VAN-SP-2
VAN-SP-3
VAN-SP-4
For measuring spindles of SP-1, SP-2, SP-6 and ELVAS-SP, experiment has verified approximate
turbulence transition situations in the following conditions:
1� SP-1 lo-vi spindle, 15 mPa
2� SP-2 lo-vi spindle, 100 mPa
3� SP-6 me-vi spindle, 100 mPa
4� ELVAS-SP, 0�85 mPa
If the rpm/mPas ratio exceeds above values, turbulent situation may occur to the spindles listed
above�
For measuring spindles ranging from VAN-SP-1 to VAN-SP-4:
Artificially higher viscosity readings may be introduced by turbulence at speeds of above 10 rpm�
