ABSTRACT:
A precision transducer for position measurements comprises a pair of supports, one of which is movable with respect to the other. Each support is provided with an electric winding constituted by equidistant serially connected printed circuit conductors extending transverse to the direction of movement. The winding of one of the supports comprises a plurality of groups of conductors connected in series and intercalated with the conductors of the other group(s). Each group of conductors is printed on one face of a substrate, the other face of which bears auxiliary conductors connecting the conductors of the groups in series, through metallized holes formed through the substrate. The substrate is bonded to the said one support after the printing of the auxiliary conductors on the said other face, the groups of conductors being printed on the said one face after the substrate has been bonded to the support.
