Shear Beam vs Compression Load Cells

Shear beam load cells are the most widely used type in commercial and industrial weighing. Their primary advantage is tolerance to off-center loading — the shear-stress sensing principle inherently rejects bending moments caused by loads not perfectly centered.

Choose shear beam when: • Building platform scales, pallet scales, or floor scales • Your application involves 4-corner weighing with summing junction • Off-center loading is unavoidable (e.g., forklifts placing loads) • Moderate capacities (50 kg to 5 tons per point) • Cost per weighing point is a consideration

JRAGRAU single-ended shear beam load cells feature IP67 protection and stainless steel construction options for food and washdown environments.

Compression load cells excel in high-capacity applications where the load path is well-defined and vertical. They offer very high stiffness (minimal deflection under load) making them ideal for rigid structures.

Choose compression when: • Your application requires capacities above 5 tons • Load is applied vertically through a well-defined load path (silo legs, press frames) • You need very low deflection under load • Material testing machines requiring high force (tension via pull-rod, compression directly) • The loading surface can be made flat and rigid

Always use self-aligning loading accessories (spherical seats) with compression load cells to compensate for any surface irregularity.
