| Abstract: | A spatial and wavelength division multi-plexing fiber Bragg grating (FBG) sensing system is reported for monitoring the temperature and the pressure (T-P) of hot water pipeline in petrochemical factory. The FBG sensing system has 72 channels independently, and it provides the capability to monitor large number sensors at same time. A resolution of 0.1 ℃ and 0.01 MPa with a measurement bandwidth of 150 Hz has been achieved. |
| Keywords: | FBG sensor sensing net temperature and pressure sensors tunable laser |
