Dynamic CSG Concrete Strain Gage Dynamic concrete strain gages measure axial strain in the concrete under high frequency (dynamic) conditions. Utilizing four active elements of a Wheatstone bridge circuit, this gage compensates for temperature, rejects bending strain (may also be configured to measure bending and reject axial strains), compensates for lead resistance and providing a sensor that is easily adaptable to most data acquisition systems without requiring additional signal conditioning. 5/16" Diameter by 8" Long Sensor Because of their low profile design, these sensors can be used in concrete pavements, columns, walls, bridge elements or wherever dynamic strains need to be measured. Each sensor is provided with end washers, nuts and are individually calibrated with standard 30-ft lead length attached (other lengths upon request) and supplied with fabrication Quality-Control documentation.
