ABSTRACT:
Load cells for weighing scales are provided with integrally formed flexures for preventing extraneous moments from affecting strain gauges secured to the load cells. The load cell itself includes in its simplest form a rectangular shaped body having cut-outs defining load carrying upper and lower arms and a vertical leg. Recessed areas are provided on opposite sides of the rectangular body between the upper and lower cut-outs to define a shear web to which strain gauges are attached. Flexure webs formed between the cut-outs in combination with further flexure webs formed at one of the ends of the load cell body effect the desired isolation.
