摘要
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 petrochemieal 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.
