  • Patent number: 4038867
    Abstract: This invention relates to a transducer assembly for measuring loads in flexible sheet material, and to a method of making the transducer assembly.A strain gauged transducer plate is bonded between first and second sheets of flexible material, and a lead out cable from the strain gauge is sandwiched between spaced, mating PTFE (polytetrafluoroethylene) tapes attached to each flexible sheet. The cable is arranged in a generally sinusoidal pattern so that the cable crosses the space between the tapes at a plurality of locations throughout the length of the tapes and so that at each location the cable crosses the space in a direction generally perpendicular to the longitudinal direction thereof, thereby preventing damage and breakage of the tapes due to operational flexing of the transducer assembly.In a preferred embodiment, the transducer plate is secured in an aperture in a woven fabric sheet which is then bonded between the flexible sheets.
