6. Phase masks, tooling to print fiber Bragg gratings

7. Phase Mask technology Phase Mask technology

8. Benefits FBG is small in size and light in weight FBG is small in size and light in weight Long operating life, immune to radiation Long operating life, immune to radiation Ideal for remote and distributed sensing Ideal for remote and distributed sensing FBG sensor is passive, draws 0 power FBG sensor is passive, draws 0 power Immune to RFI and EMI Immune to RFI and EMI Can work in hostile environment, like extreme temperature Can work in hostile environment, like extreme temperature

9. Twin gratings Cavity

10. FBG Cavity Reflection Spectrum showing all the fringes

11. Packaged to protect against dust oil and humidity, improved sensitivity

12. Packaged SEW vibration sensor Packaged SEW vibration sensor

13. VibroFibre™ Installed on Generator Radial Sensor capsule glued to end winding cap

14. VibroFibre™ Installed on Generator Tangential Sensor capsule glued to side of end winding cap

15. Top view of the designed Partial Discharge (PD) sensor Stress relief Optic fiber

16. Dimensions are in mms connectors will come out of both sides and the length will be shorter

17. PD Emulator PD Emulator

18. Working principle of the proximity & non-contact vibration sensor Measured air gap distance FBG air-gap sensor Test target or noncontact Vibration Working distance

19. Measures small displacement as fringe movements with micron resolutions

20. Mounted on an optical platform

21. Measures broad range of vibration non contact (both high and low frequency)

22. Low frequency vibration (0.1Hz) 时域 detected Applied 时间 输出电压
