Structural Crack Detectors

GAO’s structural crack detectors are devices or systems designed to detect cracks or damage in structural components of buildings, bridges, pipelines, and other infrastructure. These detectors are used to monitor and assess the health of structures, identify potential problems, and facilitate timely repairs to prevent further damage or failure.

GAO’s structural crack detectors are composed of sensors, data acquisition system, power source, display or output device, mounting hardware, and communication equipment.

The other common names for crack detectors are fracture sensors, fault detectors, flaw identifiers, breakage detectors, defect finders, imperfection sensors, damage detectors, flaw detectors, weakness identifiers, break detectors, deficiency sensors, fault finders, damage identifiers, and fracture detectors.
