Installing optical strain gages
NOTE
The fiber may be bent only after having been fixed with X60 superglue (see figure
4.2.7), however, it must not be bent at the point where the fiber protrudes from the
strain gage or the splice.
If the fibers form an arch when laid, the radius must be no less than 25 mm.
Securely fasten the fibers with adhesive tape, or similar. (Fig. 4.1.5)
Fig. 4.1.5: Fixing the outgoing fibers to relieve the strain
A piece of adhesive tape is attached to the optical strain gage at right-angles
to the fiber; this can be pressed onto the component. This fixes the strain
gage to the measurement object. At the same time, you must make sure that
the optical strain gage is positioned exactly.
You can now remove the adhesive strip attached to the optical strain gage in
the direction of the fibers. (Fig. 4.1.6)
