Strain Gage

Strain Gages are a vital geotechnical sensor that measures strain in underground cavities, tunnels, buildings, concrete, masonry dams, bridges, embedment in soil/concrete, etc. It is a resistance that varies with applied force, as it converts force, pressure, tension, weight, etc., into a change in measurable electrical resistance. Stress is determined as the object's internal resisting forces, and strain is defined as the displacement and deformation that occur.
