Strain Gage

A strain gauge is a device used to measure the strain or deformation of an object. It is commonly used in physical properties testing and inspection to determine the mechanical behavior of materials under different conditions.

A strain gauge consists of a thin wire or foil that is attached to the surface of the object being tested. When the object is subjected to stress or strain, the wire or foil deforms, causing a change in its electrical resistance. This change in resistance is then measured and used to calculate the strain or deformation of the object.

Strain gauges are widely used in various industries, including aerospace, automotive, civil engineering, and materials testing. They can be used to measure strain in structures, such as bridges and buildings, as well as in mechanical components, such as engines and turbines.

Instruments and laboratory equipment that are used in conjunction with strain gauges include data acquisition systems, signal conditioners, and strain gauge amplifiers. These devices help to accurately measure and analyze the strain data obtained from the strain gauges.

Overall, strain gauges are essential tools in physical properties testing and inspection, providing valuable information about the mechanical behavior of materials and structures.
