摘要与影响
A spatial and wavelength division multiplexing fiber Bragg grating (FBG) sensing system for monitor the temperature and the pressure (T-P) of hot water pipeline in petrochemical factory is reported. 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°C and 0.01 MPa with a measurement bandwidth of 150 Hz has been achieved.
