Study of a high-temperature and high-pressure FBG sensor with Al2O3 thin-wall tube substrate
A fiber Bragg grating （FBG） high-temperature and high pressure sensor has been designed and fabricated by using the Al2O3 thin-wall tube as a substrate. The test results show that the sensor can withstand a pressure range of 0-45 MPa and a temperature range of-10-300 ℃, and has a pressure sensitivit...

| Zusammenfassung: | A fiber Bragg grating （FBG） high-temperature and high pressure sensor has been designed and fabricated by using the Al2O3 thin-wall tube as a substrate. The test results show that the sensor can withstand a pressure range of 0-45 MPa and a temperature range of-10-300 ℃, and has a pressure sensitivity of 0.0426 nm/MPa and a temperature sensitivity of 0.0112 nm/℃ |
