This product allows the accurate determination of the specimen deflection applying third- or four-point loading beyond the load maximum, exclusive secondary deformation effects.

As measurement feeders two inductive displacement transducers with a maximum displacement path of ± 10 mm are used. The maximum linearity error of the transducers amounts 0,2%.
