Dynamic Concrete Strain Gage
AGI’s Dynamic Concrete Strain Gage (CSG) is a concrete embeddable strain gage designed for use in high frequency (dynamic) environments. These rugged, gages are ideal for infrastructure, and structural health monitoring applications with high levels of environmental noise. Our Dynamic CSGs utilize a Wheatstone bridge circuit, which compensates for temperature and lead resistance, and filter unwanted noise for precision strain measurements. Units are offered in either bending strain or axial strain configurations (please specify per order), and are easily implemented into conventional data acquisition systems. AGI’s Dynamic CSGs are a perfect choice for measuring strains in pavement, columns, bridge components and other concrete structural components.
