Product description

Strain gauges are widely used in many measurement applications, both static and dynamic. A strain gauge is sometimes referred to as an electrical resistance strain gauge, or simply a resistance strain gauge.

They are also used in dynamic measurement applications where the output fluctuates significantly due to deformation of the tested mechanical object. They are commonly used for components subjected to stress and torsion.

“Strain” is defined as the ratio of the change in an object’s length to its original length. A strain gauge measures the strain induced by an external force and converts it into an electrical signal that can later be digitized, displayed, logged, and analyzed.
