Optical rosette

K-OR - Optical strain gauge rosette: Small and rugged

Do you want to perform component tests at high strain levels and a large number of load cycles? Do you need precise test results in potentially explosive atmospheres? The HBM FiberSensing K-OR is a fiber Bragg technology-based strain gauge rosette - one of the smallest in the world, however, tolerating extreme loads.

Precise results - even in adverse environments

Since optical strain gauges do not require any electrical signals, they open up new opportunities for use in experimental stress analysis. Unlike linear optical strain gauges, K-OR - comprising three strain gauges - measures strain in three directions. This enables the absolute value and direction of mechanical stresses to be determined in the same way as with electrical strain gauges. Specially tested for applications with a strain of +/- 5000 µm/m and 10 million load cycles, K-OR in addition withstands extremely adverse ambient conditions.

The optical rosette is highly suitable for measurements

  • In potentially explosive atmospheres
  • In areas where there is high voltage or
  • Powerful electromagnetic interference as well as for
  • Materials testing, for example, on the rotor blades of wind power plants.

Easy installation and fast wiring

The installation effort of optical strain gauges such as K-OR is similar to that of electrical strain gauges. Wiring, however, is less complex, because optical strain gauges enable multiple sensors to be connected in one optical fiber.

Candid data sheets: We keep our promises.

Precision in series: This also applies to the accuracy of the values specified in our data sheets. Ideal conditions can often be theoretically attained based on the values given, but our data sheets focus on realistic standard assumptions - such as those likely to be encountered in your application. Therefore, please consider this when comparing our data sheets with those of other manufacturers.
