I want to know the measurement principle of weight sensors and load cells.

Our weight sensor and load cell use a strain gauge for measurement.
The resistance foil is attached to the steel material, and the shape that changes when a load is applied changes as the output value, and the weight value is measured.

STS internal structure is cantilevered in the load cell
The internal structure of the STS is fixed to the upper and lower plates in a cantilevered state on the load cell.

Load cell
Load cell Make a hole so that the steel material is easily distorted, attach a resistance foil, convert the load into an electric signal, and measure.

When a hole is made in the steel material and a load is applied Make it easy to bend, take a space in a cantilevered state, and fix it to the upper and lower plates
Make a hole in the steel material so that it bends easily when a load is applied, leave space in the cantilevered state, and fix it to the upper and lower plates.
