  　　Shear beam load cells, although they may look similar at first glance, they work slightly differently. A groove is machined on each side of the load cell, leaving a relatively thin vertical web in the center. This makes the cross-sectional appearance of the load cell resemble structural I-beams seen in buildings, and like them, most of the shear strain is concentrated on this thinner vertical web. Strain gauges are installed on the side of the web at a 45-degree angle to detect strain. At the same time, the top and bottom flanges help resist any moment or bending.

  　　The shear beam load cell has become very popular in medium and high volume applications, with excellent lateral force resistance. Since the webs need to be made thin enough to obtain the necessary strain level, they are usually not made for low capacity. Bent beams and single-point load cells are more suitable for this use case.
