They are small and unassuming but essential in many sectors; in many areas of industry, load cells ensure accurate determination of the contents or fill levels of containers, tanks, silos and vehicles. They frequently serve as the basis for invoicing of delivered or received amounts and, in comparison with other technologies, deliver precise and reliable measurement results regardless of the shape of the tank or the characteristics of the material inside the tank. Unlike other methods, load cells do not require regular maintenance or recalibration and are extremely robust and durable. It therefore comes as no surprise that they have been a staple of industrial weighing for a long time.
