WEIGHING APPARATUS AND METHOD

摘要

A spring formed as a Roberval-based frame of conventional material is combined with a smaller sensor in the form of a deflectable load cell of material such as a ceramic. The combination associates the higher load capacity spring with the sensor capable of performing in a manner substantially free of system error. A method for configuring the assembly for optimal system error rejection is described wherein a transmission beam carrying out a load sharing function exhibits a stress selectively greater than the average stress exhibited by the spring.
