1. A load cell for metallic silos, comprising:
a bottom base plate configured to support the load call on a ground surface;
a top plate configured to receive support a portion of a metallic silo to be weighed;
a flexible element comprising at least one extensometer;
a spacer interposed between said bottom plate and said flexible element, wherein said load cell comprises a monobloc structure, comprising said bottom plate, said top plate and said flexible element,
wherein said monobloc structure comprises ground fastening means comprising four holes, arranged respectively in proximity of the four corners of said monobloc structure, and four corresponding screws, adapted to co-act stably with four corresponding threaded bushings provided in holes produced in said ground surface, and
wherein said monobloc structure is substantially parallelepiped in shape, having two longer sides and two shorter sides, and two of said four holes extend to intercept a same side of said monobloc structure, so that the load cell is easily removable from below the silos by removing only two of the screws.
