Strain gauges (resistance strain gage) can work on the strain components that change size converted into resistance change of the converter (also known as resistance strain gauges), referred to as strain gauges. Generally sensitive gate, wire, adhesive, substrate and cover composition. strain gauges are used in many situations. Different applications place different requirements on the gauge. In most cases the orientation of the strain gauge is significant.

  Strain gauges installed on the component surface, the surface component in the load generated by the small deformation (elongation or shortening), will make the sensitive strain gauge grid is deformed, the resistance of the strain gauge changes in their rates of change and installation Department component strain gauge strain

  Strain gauge is a device used to measure the strain of 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 deformed, causing its electrical resistance to change. This resistance change, usually measured using a Wheatstone bridge, is related to the strain by the quantity known as the gauge factor.
