<p>An extensometer having a pair of platforms movable relative to each other by a guide pin and guide sleeve arrangement. The platforms are substantially U-shaped with the guide pins arranged on points diametrically opposed to each other. An inductive displacement recorder comprising a ferromagnetic core secured to one of the platforms and a coil system secured to the other platform is arranged for telescoping movement with respect to each other. A clamp is mounted on each of the platforms and arranged for securement to a sample to be tensile tested so that the extensometer, which forms a cage construction, is concentrically secured to the sample to be tested.</p> |
