A total of two aluminium-based and two rubber-based diaphragm FBG pressure sensors were fitted on a pipe with various leak points and sizes. Calibration test results showed that rubber-based diaphragm FBG pressure sensors are 30 times much higher as compared to aluminium-based diaphragm FBG pressure sensors at 93.2 pm/kPa and 96.6 pm/kPa. For leak localization test using negative pressure wave (NPW), rubber-based diaphragm FBG pressure sensors capable to localize accurately the leak location with percentage of error less than 10 . This is due to the high pressure resolution produced by the rubber-based diaphragm FBG pressure sensors. © 2024 Elsevier Inc. date: 2024 official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85183454041&doi=10.1016%2fj.yofte.2024.103687&partnerID=40&md5=b16b2b239f3356e08552576215af1440 id_number: 10.1016/j.yofte.2024.103687 full_text_status: none publication: Optical Fiber Technology volume: 83 refereed: TRUE citation: Vorathin, E. and Choong, M.X. and Mohammad, M. and Othman, A.R. and Ismail, A.R.
