Description

nnnn

The os3610 Surface Mount Strain Sensor measures average strain over the length of the

nnnn

gage while providing integrated temperature compensation. It is based on fiber Bragg

nnnn

grating (FBG) technology. The os3610 is intended exclusively for surface mounting. Each

nnnn

end of the os3610 is attached to the structure via rigid brackets that are either welded,

nnnn

bolted, epoxied, or grouted to the surface of a concrete, rock, steel, composite, or other

nnnn

structure.

nnnn

Armored cables, a rugged sealed steel body, and optional connector protection fittings

nnnn

make the os3610 suitable for harsh environments. Two FBGs are well protected inside

nnnn

the os3610 body. One FBG measures strain, and the other provides for integrated

nnnn

temperature compensation. Since there are no epoxies holding the fiber to the carrier,

nnnn

long-term stability is ensured by design

nnnn

Connector Protection Fitting

nnnn

h side-by-side comparisons with vibrating wire and foil strain gages, the os3610 is

nnnn

equally sensitive and accurate, while providing corrosion insensitivity and 100 times

nnnn

more fatigue life. The os3610 strain gage is qualified for use in harsh environments and

nnnn

delivers the many advantages inherent to all FBG based sensors

nnnn

This sensor can be used alone or in series as a part of an FBG sensor array. Installation

nnnn

and cabling for such arrays is much less expensive and less cumbersome than compa-

nnnn

rable electronic gage networks
