ABSTRACT:
A load cell assembly having a predetermined overall stiffness and a mounting plate for reducing the apparent stiffness of the load cell assembly to that predetermined level are disclosed. A load cell is mounted on a base by a mounting plate so that the load cell is fixed with respect to mechanical ground yet is free to deflect under load. The overall stiffness of the assembly is reduced to a predetermined stiffness by selecting the resiliency of the mounting plate in accordance with the stiffness of the load cell. The resilience of the load cell may be determined by either undercutting the mounting plate or by proper selection of materials. An apparatus for protecting the scale from overloads and shock loads is also disclosed.
