The OS3155 is a rugged optical strain gage with integrated temperature compensation based on fiber Bragg grating (FBG) technology. The sensor is attached on the structure by spotwelding.
In side by side comparisons with foil strain gages, the OS3155 is equally sensitive and accurate, while providing for greater strain range and 100 times more fatigue life. This sensor can be used alone or in series as a part of an FBG sensor array. Installation and cabling for such arrays is much less expensive and cumbersome than comparable electronic gage networks. Multiple optical strain gages can be arranged in close proximity at 0, 45 and 90 degrees for strain rosette measurements.
