Strain-gauge and method for its manufacturing

摘要

The gauge includes a measurement grid (2) on a carrier foil (1) carrying a cover with a layer (6) of insulating material and a another layer (7) of metallic material. The metallic layer of the covering is a foil whose extent in the cover plane is less than or equal to that of the carrier foil. The foil forming the metal layer and the carrier foil have two common separating edges. An intermediate layer, pref. of adhesive material, is arranged between the insulating and metallic layers. Alignment markings can be made on or through the metallic layer.
