Product Description The os3610 is based on fiber Bragg grating (FBG) technology and is available two gage lengths of 25 or 100 cm. It is intended exclusively for surface mounting. Each end of the os3610 is attached to the structure via rigid brackets that are either welded, bolted, epoxied, or grouted to the surface of a concrete, rock, steel, composite, or other structure.
Armored cables, a rugged sealed steel body, and optional connector protection fittings make the os3610 suitable for harsh environments. Two FBGs are well protected inside the os3610 body. One FBG measures strain, and the other provides for integrated temperature compensation. Since there are no epoxies holding the fiber to the carrier, long-term stability is ensured by design.
In side-by-side comparisons with vibrating wire and foil strain gages, the os3610 is equally sensitive and accurate, while providing corrosion insensitivity and 100 times more fatigue life. The os3610 strain gage is qualified for use in harsh environments and delivers the many advantages inherent to all FBG based sensors.
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 less cumbersome than comparable electronic gage networks.
