13. Packaged to protect against dust oil and humidity

14. Packaged SEW vibration sensor

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

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

17. Twin cavity sensor provides temperature compensation

18. A DBR fiber laser sensor is a Vibrofibre with Active fiber cavity

19. Top view of the designed PD sensor actual unit will have both an input and an output Stress relief Optic fiber

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

21. PD Emulator

22. It features high signal to noise ratio

23. This signal to noise is generated by the optical gain of the special fiber cavity

24. Working principle of the air gap sensor Target FBG collimator Air gap Hybrid cavity

25. Measure small displacement as fringe movements 输出电压 时间

26. Mounted on an optical paltform

27. Measures broad range of vibration non contact

28. Low frequency vibration 时域 施加 检测 输出电压 时间

29. Distributed temperature and low frequency vibration measurement • Use of FDM technology • The interrogation unit is a separate subsystem • Sensing elements consist of an FBG array each element has an identical center wavelength • The array can be up to 200 elements each

30. Each sensor box contains 2 fiber coils Vibration Fiber loops FBG, l Distributed Vibro Sensor Box D > 5 m Vibro Sensor Box Distributed Vibro Sensor Array

31. FDM Technology: Generating a Chirped waveform by scanning the laser current

32. The various frequencies act as labels on all the FBG sensors

33. The sensor array (sensor spacing does not need to be regular)

34. The spectrum of a single sensing element.

35. Design of the broad band triangular grating for demodulation

36. Shift in center wavelength due to vibration and temperature, vibrations will be periodic

37. Output voltage amplitude change can be related to temperature or strain
