What Is a Strain Gauge?

Strain gauges are composed of sensitive grids and other components for measuring strain. The working principle of the resistance strain gauge is based on the strain effect, that is, when a conductor or a semiconductor material undergoes mechanical deformation under the action of an external force, its resistance value changes accordingly. This phenomenon is called "strain effect".

There are many types of strain gauges. A typical strain gauge is a plastic film (15-16m) called a substrate that is pasted with a sensitive grid (3-6m) made of thin metal foil, and then covered with a film to make a laminated structure. ^[1]

1. Some strain gages have a self-compensation function, and the function of suppressing the temperature drift of the strain itself is not required for the compensation sheet.
2. There are many types of products, which can provide customers with perfect strain measurement options in different measurement occasions, including: ordinary, low temperature, high temperature, ultra high temperature waterproof, composite materials, concrete, welding type, welding waterproof, semiconductor, residual stress measurement , Etc. Very complete product specifications and models.
3. Wide measuring temperature range: -269 -800
4, good product stability, long-term measurement, product measurement results are stable.
5. The product has various measurement shapes, and can measure a variety of mechanical signals, such as: measurement of torque, shear stress, concentrated stress, and so on. ^[1]

Strain gauges make good use of

Strain gauges are mainly used in sensors. The effect of vibration aging depends on the choice of mode. To ensure that the residual stress in key parts of the workpiece is accurately eliminated or reduced, and welding, cutting, casting, forging, and deformation and cracking of machined parts are prevented. Sigmar has developed a variety of conventional aging equipment that can provide users with scientific process shape analysis and convenient equipment operation functions in order to qualitatively guarantee the aging process effect ... They can be divided into 4 series and 16 specifications. ^[2]
