What is Strain Gauge -Types Of Strain Gauge

A strain gauge (also spelled strain gage) is a device used to measure strain on an object. Invented by Edward E. Simmons and Arthur C. Ruge in 1938, the most common type of strain gauge consists of an insulating flexible backing which supports a metallic foil pattern. The gauge is attached to the object by a suitable adhesive, such as cyanoacrylate. As the object is deformed, the foil is. The strain gauge is mounted by coupling it to the object to be inspected. Both the object and the strain gauge are deformed when a load is applied. Strain gauges measure strain from different types of stresses, namely tensile, compressive, bending, torsional, and shear stress.
