How does the weighing transducer work?

　　First of all, we need to understand the physics and material science behind the working principle of weighing transducer, which is a strain gauge (sometimes called a strain gauge). A metal foil strain gauge is a material whose resistance changes with applied force. In other words, it converts (or converts) force, pressure, tension, compression, torque, weight, etc. into changes in resistance, which can then be measured. Therefore, the metal foil strain gauge is the cornerstone of the working principle of weighing transducer. The use of strain gauge bridges for weight measurement is also one of the review applications of this technology.

　　Strain gauges are electrical conductors that are tightly attached to the film in a zigzag shape. When this film is pulled, it — and the conductor — stretches and stretches. When it is pushed, it shrinks and becomes shorter. This change in shape causes the resistance in the electrical conductor to also change. The strain applied in the weighing transducer can be determined based on this principle, because the strain gauge resistance increases with the applied strain and decreases with the contraction.
