Surface Mount Strain Sensor

The os3510, based on fiber Bragg grating (FBG) technology, is intended exclusively for surface mounting. Each end of the os3510 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.

A rugged, stainless steel body, ruggedized cables and optional connector protection fittings make the os3510 suitable for harsh environments. Two FBGs are well protected inside the os3510 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 os3510 is equally sensitive and accurate, while providing 100 times more fatigue life. The os3510 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.
