Optical Strain Gages

Experimental stress analysis is a typical application for optical strain gages (SG) based on so-called fiber Bragg gratings, such as the K-OL and K-OR types from HBM. As the strains are measured by light, optical strain gages dispense with electrical signals, allowing them to be used under difficult conditions such as under high voltage, when there is powerful magnetic interference or in potentially explosive atmospheres. For its type K-OL and K-OR optical strain gages, the company now provides the K-OTC sensor, which can be used to compensate the temperature response of optical SGs. The signal of the sensor is read into the catman AP software together with the signals of the optical strain gages, and compensation occurs automatically.
