MiniProf Wheel 400

Home > Solutions > MiniProf > Wheel 400

The MiniProf Wheel 400 performs the same functions and precision quality as the MiniProf Wheel, but with an extended 400mm backplate. The wider backplate increases the diameter reading capability and is three times less sensitive to the state of the wheel and the measuring process.

Wheel diameter calculations are based on the Versine principle, alongside the assumption of an ideal wheel without local deformations. Please note, diameter readings should be considered as they can be impacted by the state of the wheel, including defects on the top of the flange alongside any incorrect positioning of the instrument.

Accuracy is better than ±9 µm with a repeatability of ±2.5 µm.
