KFEM Series Ultra high-elongation Foil Strain Gages
KFEM series ultrahigh-elongation foil gages is made up of polyimide and resistive material of CuNi alloy foil. It can measure strain in elastic to plastic region on structures and are suitable for large strain measurement or rupture tests of metals (Steel, stainless steel, aluminum) and plastics (Polyethylene, polypropylene). It is able to measure 20 to 30% of material deformation at normal temperature. The laminate protruded from the tip of gage base ensures improved adhesive property, making the gages hard to peel off. The foil material has an improved elongation property and is hard to disconnect. Besides the silver-clad copper lead wire, KFEM strain gages with pre-attached lead cables are available on request.
