ABSTRACT:
The rod-shaped load cell consists of a guide section (1), which is subdivided into a frame (6) and a load-bearing element (7), and two parallel, rigid plates (8) connecting the two cited elements. Plates (8) are connected to both frame (6) and load-bearing element (7) by band-shaped flexural joints (9) which extend across the overall length of guide section (1). The load cell rests via frame (6) upon two feet (2) located outermost on rod-shaped guide section (1). The platform (5) rests upon two mounting elements (3) also located outermost on guide section (1), with the mounting elements (3) acting on load-bearing element (7). A force sensor (4) is diagonally installed at half the length of guide section (1). When platform (5) is loaded, tensile force acts upon force sensor (4) (see FIG. 1).
