Strain gauges are widely used in many measurement applications both static and dynamic. A strain gauge is also sometimes called an electrical resistance strain gauge or simply a resistance strain gauge. They are also used in dynamic measurement applications where output fluctuates greatly due to deformation of a mechanical object under test. It is widely used for objects subjected to stress and torsion. The property called “strain” is the ratio of the change in length of an object to its original length. A strain gauge can measure this amount of change caused by an external force and convert it into an electrical signal that can then be converted to digital values, displayed, collected and analysed.
The Weldable Resistive/Embedded Type Strain Gauge has a structure consisting of a stainless steel body with a strain gauge embedded inside and two ears placed at the ends of the body. In embedded applications, the strain effects that occur in the cross-section after the mounting process, either on the steel surfaces or on the stress in mass concrete, are transmitted to the body and the strain gauge. The mechanical change, together with the instantaneous strain changes that occur, is reflected as a signal output to the measurement unit. Depending on the scaling factor, deformation or stress in the section can be easily calculated.
