Scale and position-measuring device
Abstract:
A scale for inductive position measurement along a measurement direction X includes a support channel made of electrically conductive material having two interconnected spaced-apart side walls extending parallel to the measurement direction X and enclosing an interstitial space therebetween. A succession of first graduations made of electrically conductive material are disposed on the support channel, located in the interstitial space opposite and spaced from one of the two side walls and extending parallel to the measurement direction X. A succession of second graduations made of electrically conductive material are disposed on the support channel, located in the interstitial space opposite and spaced from the other one of the two side walls and extending parallel to the measurement direction X. The succession of first graduations and the succession of second graduations form a gap configured to receive a scanner operable to inductively scan the first graduations and the second graduations.
