-When a metal material is subjected to tension, the metal material becomes thinner and the electrical impedance increases; conversely, when it is compressed, the metal impedance becomes smaller, and the strain gauge made by this method is called a weighing module. This type of sensing device can transform the pressure of physical phenomena into electrical signal output, so it is often used in load, tension and pressure conversion applications. |
|
3 |
+Electrical resistance of metal material changes in proportion to the forces being applied to deform it. The strain gauge measures the deformation as a change in electrical resistance, which is a measure of the strain and hence the applied forces (load). |
