FAQ. How reliable are FBG sensors?

Optical fibre fatigue reliability is very high and FBG sensors benefit from this fact. For instance, client tests found that Smart Fibres’ SmartPatch sensors were still 100 % functional after 6 x10⁷ cycles of tensile and compressive fatigue loading.

SmartRod - (Product Concept)

A prototype FBG sensor array in a pultruded composite rod for the measurement of curvature, tension, torsion and compression.

SmartPort

A low profile, fibre optic P/T gauge for distributed pressure sensing in hydrocarbon wells and other extreme harsh environments.

SmartBar

A long gauge optical strain sensor encased in a steel rebar. Suitable for e.g. concrete embedment.

SmartAccel-LF

A single axis FBG acceleration sensor, suitable for the measurement of low frequency vibrations.

SmartWeld

A weldable strain sensor for metallic structure monitoring. Hermetically sealed variant available.

SmartTemp

A temperature sensor available in several styles to suit different applications. Can be supplied singly or in arrays.

SmartTape

A low profile strain / temperature sensor supplied within a veil cloth suitable for composite embedment or surface bonding.

SmartPatch

A robust, surface bonded strain / temperature sensor supplied as a flexible FRP patch. Available to purchase together with a Smart Fibres interrogator.

SmartFBG

An unpackaged FBG sensor supplied in a single mode optical fibre for strain and temperature measurements. Available to purchase together with a Smart Fibres interrogator.
