N2 - FBG sensors are more and more accepted in most area of Structure Health Monitoring. However, due to the fact that FBG senses both strain and temperature is monitored simultaneously, temperature compensation for FBG strain sensors of long-term structural monitoring is indispensable. In this paper, based on the FBG's strain and temperature sensing principles, a novel FBG-based sensor for simultaneous dual-measurement of pressure and temperature has been developed. Firstly, in consideration of the requirement of sensors, a novel sensor structure has been designed and its sensing principle is given in details. Secondly, the properties of FBG-based sensor for simultaneous dual-measurement of pressure have been tested by some experiments. Finally, theoretical sensitivity has been compared with that from experiments. The research results show that the FBG-based sensor for simultaneous dual-measurement of pressure has good linearity, repetition, immunity of temperature changes. Such kind of FBG-based sensor for simultaneous dual-measurement of pressure can be used to practical monitors.
