3 Product Description
3.1 Functional Description
3.1.1 Function
The fos4Strain patch is a fiber-optica strain sensor based on a fiber Bragg grating.
The sensor is designed for strain monitoring of various structures, for examp e GRP,
meta and concrete.
The sensor is suitab e for measurements under difficu t conditions as the functiona
princip e makes the sensor immune to e ectromagnetic interference and ightning.
3.1.2 Overview

1Measuring range
Figure 3: App ying the adhesive
1Bottom side of the sensor 2Adhesive
The position of the measuring range is se ected so that a defined strain of the
structure is measured. See Fig. 2: Center of the measuring range, page 12.
The surface of the structure is prepared so that the surface is flat, dust-free and dry.
ergo. 1665 is app ied to the underside of the sensor. See Fig. 3: Applying the adhesive,
page 12.
The sensor is g ued to the structure.
For optima curing of the adhesive, the sensor is attached during curing. The
curing time (functiona y stab e after 13 min at 12 … 25 °C) depends on the ambient
temperature.
The sensor is connected to a compatib e measuring device.
The wave ength of the sensor can then be used to determine the strain of the
structure. See Calculation of strain, page 13.

3. Product Description
3.1.4 Calculation of strain
The strain ε is ca cu ated on the basis of the measured wave ength λ as fo ows:
With the rest wave ength λ0, CTE αS, temperature change ΔT, k-factor k = 0.79 ± 0.5
and the thermo-optica effect αn = 5.56 ± 0.40 µm/m/K.
αS is composed of the CTE of the substrate and the sensor.
αS must be determined separate y for each app ication
The fo owing va ues were determined in the aboratory for a uminum and g ass:
■αS, A u = 23.83 ± 0.14 µm/m/K
■αS, G = 12.43 ± 0.73 µm/m/K
