IS THE ARCHIMEDE HR SUITABLE
TO MEASURE ALL KINDS OF LARGE DIAMETERS?
Archimede HR is a device that due to its given flexibility, can be used in many production
fields. Its measurement principle allows to obtain the stated accuracy when measuring
cylindrical parts that do not have irregular shapes, such as those machined. The uncer-
tainty in the diameter measurement is directly influenced by the shape of the cylinder.
This means that, in order to achieve with Archimede an accurate measurement of a
cylindrical piece with a 1000 mm diameter, this must have a reduced circularity error.
Otherwise it becomes necessary to perform several measurements on the circumference
and detect the value of the average diameter.

Archimede Uncertainty
However, it is possible to measure an irregular cylinder repeating the measurement
on different arcs of the same cylinder, to obtain the value of the average diameter.
In any case, the max accuracy of measurement for Archimede is shown in Tab.1
