newLight FS70 Multiple Fiber Bragg Gratings

Based on the Fiber Bragg Grating (FBG) technology and the newLight optical sensor series, the FS70 configurable arrays are optical fibers with multiple FBGs and high-performance coatings. These are optimally suited for multipoint measurement of strain in laboratories and in all kinds of industries.

To maximize results, these can be configured with a selection of options:

Selectable number of FBGs, wavelengths, and distances
Selectable cable types: braid, aramid, armor or no cable
Selectable connector type: FC/APC or SC/APC or no connector

Precise

Accurate measurements on curved surfaces
Long-term stability without drift
Immunity to all electromagnetic interferences

Precise measurement results with long-term stability

Resistant

High resistance to fatigue
Outstanding bending capability
Resistance to corrosion, also in humid and salty environments
Fewer cabling requirements

Extremely resilient and suited to indoor and outdoor applications

Convenient

Single, ready-to-install optical fiber
Light-weight optical fibers and reduced cabling
Fitted for hybrid measurements (optical and conventional)

Easy-to-use with little installation effort
