Title:
LOAD CELL, SCALE, AND STRAIN SENSOR
Document Type and Number:
Japanese Patent JP2022133175
Kind Code:
A
Abstract:
To provide a load cell, a scale, and a strain sensor capable of suppressing measurement errors caused by usage conditions.SOLUTION: A load cell includes a strain generator having a strain generation part that connects a fixed part and a load receiver and elastically deforms with the displacement of the load receiver. The load cell includes a first strain gauge arranged at a site on the surface of the strain generation part adjacent to the fixed part, a second strain gauge arranged at a site on the surface of the strain generation part adjacent to the load receiver, and a third strain gauge arranged at a site on the back surface of the strain generation part adjacent to the load receiver. The load cell includes a fourth strain gauge arranged at a site on the back side of the strain generation part close to the fixed part, a first series circuit in which the first strain gauge and the third strain gauge are connected in series, and a second series circuit in which the second strain gauge and the fourth strain gauge are connected in series.SELECTED DRAWING: Figure 9
