Description

ROCTEST’s FOS fiber-optic strain gauges are the best choice for high-performance strain measurements. The strain gauge measures the expansion and contraction of material due to mechanical stress or thermal effect.

The strain gauges are designed around a Fabry-Perot interferometer (FPI). When bonded to a specimen, the strain transferred to the gauge is converted into engineering units by the readout.

FOS strain gauges are insensitive to any pulling or manipulation of the incoming fiber. This feature is advantageous when the gauge is embedded in composite materials. Long-term reliability of the gauge length is guaranteed by the welding method that avoids any internal creep that may arise from the use of adhesives.
