Measurement of a plane with a precision spirit level
It is possible to measure a plane with a spirit level system
very accurate. The system itself measures a angle which has to be
transformed into a height. By moving the µLevel over the surface you
receive the relation between all measured points. In the picture above
you can see the measured values in µm/m
By knowing
the measurement-length it is possible to calculate a difference in the
height. By adding all the height-differences you are able to express a
straightness.
