The K-OR Type optical strain gauge from HBM Inc., Marlboro, MA, is a Fiber Bragg grating-based strain gauge rosette designed to sense strain as it occurs. The rosette comprises three measuring grids at angles of 0°, 60°, and 120°, enabling the absolute value and direction of the mechanical stresses to be defined. The 43 by 47 mm rosette can be used to test fiber composites, and is capable of tests of up to 10 million load cycles with a strain of ±5.000 µm/m. Applications include strain measurement in potentially explosive atmospheres and areas where there are high voltages or powerful EMI.
