Surface Mount Strain Sensor

The os3610, based on fiber Bragg grating (FBG) technology and intended exclusively for surface mounting, is available in gage lengths of 25 and 100 cm. 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 concrete, rock, steel, composite, or other structure.

A rugged, stainless steel body, ruggedized cables 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, longterm 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 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 sensor.

This sensor can be used alone or in series as part of an FBG sensor array. Installation and cabling for such arrays is much less expensive and less cumbersome than comparable electronic gage networks.
