Optical Strain Gage

The os3100 Optical Strain Gage is designed to make fiber handling easy and sensor installation fast and repeatable. Its stainless steel carrier holds the FBG in tension, using no epoxy, and protects the fiber during installation. For temperature compensation, the os3100 may be connected in series with an os4100 FBG Temperature Compensation Gage or an os4350 FBG Temperature Sensors.

Two mounting options provide for either weld or epoxy attachment to a structure’s surface. Installation time is just a few minutes with welded gages which can be used immediately after attachment. Epoxy gages typically cure in less than 24 hours at room temperature, similar to electronic foil strain gages.

与金属箔应变式并排比较, the os3100 is equally sensitive and accurate, while providing for greater strain range and 100 times more fatigue life. The os3100 strain gage is qualified for use in harsh environments and delivers the many advantages inherent to fiber optic sensors.
