Scale and method for producing this scale and position measuring system employing such a scale
First Claim
1. A scale, comprising:
- a first base body comprising;
a first non-magnetizable support; and
a first set of magnetic elements that are arranged laterally next to said first non-magnetizable support, are magnetized in a single identical direction and are arranged in a measuring direction;
a second base body comprising;
a second non-magnetizable support; and
a second set of magnetic elements that are arranged laterally next to said second non-magnetizable support, are magnetized in said single identical direction and area arranged in said measuring direction; and
wherein said first base body and said second base body are put together such that in said measuring direction alternating ones of said first and second sets of magnetic elements are arranged and said first and second sets of magnetic elements have different magnetic orientations with respect to each other.

Abstract
A scale that includes a first base body having a first non-magnetizable support and a first set of magnetic elements that are arranged laterally next to the first non-magnetizable support, are magnetized in a single identical direction and are arranged in a measuring direction. A second base body having a second non-magnetizable support and a second set of magnetic elements that are arranged laterally next to the second non-magnetizable support, are magnetized in the single identical direction and area arranged in the measuring direction. The first base body and the second base body are put together such that in the measuring direction alternating ones of the first and second sets of magnetic elements are arranged and the first and second sets of magnetic elements have different magnetic orientations with respect to each other.

11. A method for producing a scale, comprising:
-
providing a first base body comprising;
a first non-magnetizable support; and
a first set of magnetic elements that are arranged laterally next to said first non-magnetizable support, are magnetized in a single identical direction and are arranged in a measuring direction;
providing a second base body comprising;
a second non-magnetizable support; and
a second set of magnetic elements that are arranged laterally next to said second non-magnetizable support, are magnetized in said single identical direction and area arranged in said measuring direction; and
combining said first base body with said second base body by sticking them together such that in said measuring direction alternating ones of said first and second sets of magnetic elements are arranged and said first and second sets of magnetic elements have different magnetic orientations with respect to each other. - View Dependent Claims (12, 13)
