2. Working Principle of Double Ended Shear Beam Load Cell
The working principle of a double-ended shear beam load cell relies on the deformation of the load cell body when a force is applied. It consists of two mounting surfaces on each end, allowing the load to be evenly distributed and reducing the effects of extraneous forces. As the force is applied, the strain gauges attached to the load cell body detect the resulting deformation and convert it into an electrical signal. This signal is then amplified and processed to provide an accurate measurement of the applied force.
