The PR 6221 range of load cells is designed exclusively for use on road weighbridges. The unique design principle, combined with the installation kits, counterbalances movements caused by mechanical or thermal expansion or contraction of the weighbridge construction. The unique combination of the selected geometry and material/surface hardness parameters guarantees perfect rolling characteristics, high restoring forces and long-term maintenance-free operation.
