CLASS 1 LASER PRODUCT
1 For the default measurement range of ±1,250 µStrain or ±200 °C; see Page 3 for detailed timing information
2 Minimum gage length is achievable using the largest measurement range, having a single-scan repeatability of ±17.0 µStrain or
±2.0 °C
3 Accuracy maintained by an internal NIST-traceable HCN gas cell
4 Temperature and strain measurements are calculated from the spectral shift of scattered laser light. Using the default conversion
coefficients of 1 GHz = 0.8 °C = 6.58 µStrain, the accuracy of temperature and strain are 0.15°C and 1.25 µStrain. [Othonos and
K Kalli, Fiber Bragg Gratings (Artech House, Boston, 1999)].
5 For the default gage length of 1 cm
6 Based on material properties of the standard sensor: polyimide-coated, low-bend-loss optical fiber. For temperatures up to 800°C,
