HBM has improved its K-OP optical strain gages (SGs). They are, for example, well suited to material tests of new fiber composites with tests of up to 10 million load cycles with an alternating strain of Â±5.000Âµm/m now
The 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 them suitable for use in explosive atmospheres, where electro-magnetic interference is present, or in high-voltage applications.
