Abstract: Disclosed is a device in the field of systems for measuring the weight of an object and in more detail concerns a load cell for metallic silos, or tanks and hoppers. The load cell for metallic silos includes: a bottom base plate for supporting it on a ground surface; a top plate for receiving and supporting a portion of a metallic silo to be weighed; a flexible element including at least one extensometer; and a spacer interposed between the bottom plate and the flexible element. Advantageously, the load cell includes a monobloc structure, substantially parallelepiped in shape, including the bottom plate, the top plate and the flexible element.
