Metodo per strumentare internamente una cella di carico estensimetrica e cella di carico estensimetrica così ottenuta

A method for internally instrumenting a strain gauge load cell, comprises: preparing a monolithic elastic element (2) of a load cell (1), wherein the monolithic elastic element (1) has a cavity (3); preparing at least one printed circuit (5) comprising at least one strain gauge (15), wherein the printed circuit (5) has a first face (11) configured to be coupled to the monolithic elastic element (2) and a second face (13) opposite the first face (11), wherein an adhesive layer (12) is placed on at least part of the first face (11) except at the strain gauge (15); applying a layer of glue (22) on the first face (11) and substantially only at the strain gauge (15); inserting the printed circuit (5) in the cavity (3), making the adhesive layer (12) adhere to an internal surface (4) of the cavity (3); pressing the strain gauge (15) against the internal surface (4) so as to make the layer of glue (22) polymerize and to stably join the strain gauge (15) to the internal surface (4).
