      In order to best understand the shear beam load cells, it is important to understand the forces they handle. Shear forces cause objects to slide from one cross-section to another, and this force can be easily seen in several daily activities. Shearing forces are used for tasks such as using scissors, shaving, painting and scrolling through touch-screen phones. On the contrary, the bending force is exactly what it sounds like-an an external force that causes an object to bend. These two forces must be considered when building almost anything (including bridges, airplanes, houses, etc.).

      Since these forces play an indispensable role in our lives, we need a shear beam load cell to accurately measure these forces. Shear and curved beams are straight blocks with one end fixed and the other end loaded, but curved beams are more compact. However, although curved beams tend to be more compact overall, for larger capacity applications, shear beams can be designed to be more compact than curved beams.

      From the outside, the shear beam element may actually be the same as the curved beam element, but there is a key difference. The shear beam element has a large hole that partially penetrates both sides, leaving only a thin and vertical net in the center of the element. This is different from the curved beam element, where the large hole in the curved beam always passes through. Since the shear force is a cross-section, the shear beam load cell provides first-class stability for the lateral force. In addition, when the application point moves within a certain range, the shear strain does not change-this means that the electrical signal that converts the force into a value is independent of the load application point.

      For bending and shear beam units, the weight is placed on the spring of the weighing unit. The force applied to the spring is then converted into electrical output by a strain gauge mounted on the spring. These beam elements have an advantage in their simplicity because the shear and bending beam elements at their core are nothing more than beams with strain gauges. These basic components can then be enhanced with additional components to protect the load cell.
