Developments in optical strain gages suit extreme requirements
HBM has improved its K-OP optical strain gages (SGs) making them highly suitable for many more applications when compared to electrical SGs. They are, for example, ideally suited to material tests of new fiber composites with tests of up to 10 million load cycles with an alternating strain of ±5.000 µm/m now possible.
K-OP optical SGs are based on so-called fiber Bragg gratings which measure strain using pure optical techniques without the need for any electrical signals. This makes the optical SGs very suitable for use in explosive atmospheres, where electro-magnetic interference is present, or in high-voltage applications without problems. In addition, several optical SGs can be attached to a fiber, enabling the implementation of parallel measurements. Glass fiber lengths of several hundred meters are possible.
Using optical SGs for data acquisition and evaluation is very simple with a complete range of components available for all applications from HBM. These range from optical SGs with the appropriate accessories via interrogators to HBMs data acquisition software catman®AP, which includes a special EasyOptics module for optical SGs.
Users receive a data sheet with optical strain gages that includes the important gage factor for each individual SG as tested by HBM to meet the latest VDI/VDE2660 requirements.
