For ambient vibration measurements on building structures, a strain gauge displacement sensor has been developed alongside two accessories that enable local relative deformations and/or curvatures of a structure to be measured at very low levels. With a resolution below 0.01 microns, the sensor has been tested in the 0–100 Hz frequency range, making it suitable for frequency measurements as well. The sensor can be mounted on the structure using magnets quickly and easily. This article presents two application examples that demonstrate the device's advantages and sensitivity. The device is intended for diagnosing damage in building structures, as relative deformations and curvatures directly reflect stresses within the structure.
