Strain gauges are widely used in many measurement applications, regardless of static or dynamic conditions. A strain gauge is sometimes referred to as an electrical resistance strain gauge or simply a resistance strain gauge. They are also used in measurement applications where the outputs fluctuate significantly due to the deformation of the tested mechanical object, which can be considered dynamic. They are commonly used for objects subjected to stress and torsion. The property referred to as "strain" is the ratio of the change in length of an object to its original length. A strain gauge can measure the amount of this change caused by an external force and convert it into an electrical signal that can be displayed, collected, and analyzed, which can later be transformed into digital values.
The Source/Embedded Electrical Resistance Type Strain Gauge has a structure consisting of a stainless steel body with a strain gauge placed inside and ears mounted at both ends of this body. In embedded applications, the strain effects experienced by the section after installation on mass concrete or steel surfaces through welding are transmitted to the body and the strain gauge. The instantaneous strain changes that occur, along with mechanical changes, are reflected as a signal output to the measurement unit. Depending on the scaling factor, the deformation or stress in the section can be easily calculated.
