WST511 truck scale or silo use Canister Compression Load Cell, Column-type load cells, with their simple structure, large measuring range, high stability, and strong resistance to off-center loading, have become the preferred solution in the field of large-tonnage weighing. Their core applications are concentrated in scenarios such as truck scales, tank weighing, and rail scales, making them an irreplaceable key component in industrial weighing and trade settlement.
FEATURES
Columnar Structure: Employs a cylindrical or square-column elastomer design, with the force direction aligned with the elastomer’s axis, resulting in a simple and compact structure.
High Stiffness Design: The elastomer boasts high stiffness, a high natural frequency, and excellent dynamic response performance.
Good Symmetry: Isotropic force distribution minimizes lateral force influence and enhances resistance to eccentric loads.
Good Sealing: Typically employs a fully welded sealing structure, achieving protection levels up to IP67/IP68, suitable for harsh environments.
