A load cell is a kind of force sensor that changes the deformation of a material into an electric signal. In short load cells are sensors that convert weight or force into electric signal. Thus, load cells are key components of any weighing system. A substantial amount of research made in the field of transducers has drastically reduced the number of instrumental errors, which, in turn, has supported the market growth.    

Analog load cells accounted for over three-fourths of the global market revenue in the same year. On the contrary, digital load cells are poised to witness superior growth during the forecast period 2017-2025. Growing need for precision weighing, especially in heavy lifting applications is expected to drive demand for digital load cells globally.

Load cells have single point load cells,shear beam load cells and compression load cells.Single point load cells are constructed with aluminum mostly. Shear beam and compression are made of steel material.According to your weighing requirement to choose the load cells , low capacity scale normaly is equipment with aluminum load cells.

Aluminum load cells are already redjusted the corner difference when the products are on the production line.It could promise the scales accuracy and avoid big error.Steel load cell could be used by more 3 as group in weighing system.It couldn’t be corrected the corner error .
