3.1.1 General Information
Number 1 in Fig. 3.1 shows the general information on
the particular sensor, such as its type, the sensor part
number, its serial number and the production tracking
number, the FBG ID.
3.1.2 Calibration Data
Under the calibration data table (number 2 in Fig. 3.1 )
there is the most important information on the strain sen­
sor: its central wavelength at room temperature and its
sensitivity – values that should be used for temperature
computation.
3.1.3 Temperature Computation
Number 3 in Fig. 3.1 exemplifies the calculations that
should be performed for wavelength measurement to
temperature conversion. The temperature variation of a
weldable temperature sensor is given by a second order
polynomial equation obtained by the sensor calibration.
