    Abstract: A radius of curvature transducer has an integrally molded body, flexible in a bending mode with two contained wire guide tubes extending the length thereof, spaced laterally from and parallel to the body neutral axis and displaced 90.degree. angularly about the neutral axis. A push-pull wire is fixed to one end of the body and extends freely through each wire guide. An LVDT sensor, having a movable core, is coupled to the free end of each push-pull wire. As the body is subjected to bending, the wires are displaced in the passages and in turn displace the moving member in the LVDT causing signal outputs indicative of the difference in length of the path along which the wire extends relative to the neutral axis. Calculations convert the signals to radius of curvature indications and indications of the coordinates of one end of the transducer body relative to the other end.
