Abstract
A member of a linear position measuring transducer is provided with a hole running parallel to its windings. In one embodiment, elements are inserted into the hole to expand or shorten the length of the transducer. In another embodiment, cutout slots are made between quadrature sections of windings and the elements are introduced into the hole to alter the relative spacing between these quadrature winding sections.
Claims1
A member of a position measuring transducer, said member being adapted for use with a transducer having two mutually spaced, relatively movable members with electrically coupled elements, said member comprising:
- a base having a plurality of electrically coupling element circuits affixed to one surface thereof, said circuits being spaced from each other by a predetermined initial spacing distance, said circuits further having a common longitudinal axis;
- wherein said base has at least one cutout portion transverse to said axis between said circuits;
- said base having an aperture therein parallel to said longitudinal axis;
- and
- means for insertion in said aperture for changing the spacing distance between said circuits.
