Description

technical field

[0001] The present invention relates to an electronic weighing scale that uses a load cell unit to measure the mass of an object to be measured placed on the upper surface of a top plate member. Background technique

[0002] In general electronic weight gauges, about four sets of load cell units are used to support the top plate member from below. The self-weight of the object to be measured placed on the top plate member is distributedly applied to the load cell unit. And, the mass of the object to be measured is measured by adding the measured values ​​on each load cell unit.

[0003] A common structure of a load cell unit is that a plurality of strain gauges (strain gauges) are pasted on a sensing portion of a so-called strain generator (strain generator). As the strain generator, a diaphragm-type strain generator, a shear beam-type strain generator, and the like are known. These strain generators have in common that when a load is applied, a strain cor...
