摘要： A strain gauge incorporating a length of wire maintained under a predetermined tension and an electric magnetic device for plucking the wire at substantially the mid point of its length, the wire being disposed in a hollow spacer tube assembly comprising an outer tube formed of a material such as ebonite which while being longitudinally compressible nevertheless has a lateral stiffness sufficient to withstand forces which may normally be expected to be applied thereto when in use, and an inner tube or liner of brass or other equivalent material made up of at least two axially aligned lengths of tube so arranged that at least one gap or space will be present in the overall length of said inner tube or liner.
