FAQ. How do I choose the correct fibre coating and FBG recoating?
Please refer to the table below as a guide.
For strain measurement we recommend to use a Polyimide recoat over the FBG due to its superior strain transfer properties.
| Measurement and environment condition | Recommended fiber coating and re-coat material |
| Strain measurement > 85 °C | Polyimide coated fiber with Polyimide recoat (P/P) |
| Strain measurement < 85 °C | Acrylate coated fiber with Polyimide recoat (A/P) |
| Temperature measurement > 85 °C | Polyimide coated fiber with Polyimide recoat (P/P) |
| Temperature measurement < 85 °C | Acrylate coated fibre with Acrylate recoat (A/A) |
