摘要：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 degrees C and 0.01MPa with a measurement bandwidth of 150Hz has been achieved.
