The working principle is based on resistance strain gauge strain effect produced, i.e., when the conductor or semiconductor material mechanical deformation under the action of external force, the resistance value of the corresponding changes, a phenomenon known as “strain effect.”
The strain gauge attached to the object to be measured, so that as the strain of the measuring object bent together, so that the inside of the metal foil is bent with the strain. Many metal when mechanically bending its resistance changes.
