A load cell is a transducer which converts force into a measurable electrical output. Although there are
many varieties of force sensors, strain gauge load cells are the most common load cell – and, except for
certain laboratory applications where precision mechanical balances are still used, strain gauge load cells
dominate the weighing industry. Pneumatic load cells are sometimes used where intrinsic safety and
hygiene are desired, and hydraulic load cells are considered in remote locations, as they do not require a
power supply. Strain gauge load cells offer accuracies from within 0.03% to 0.25% full scale and are
suitable for almost all industrial applications.
