In this paper, a novel long-period fiber grating(LPFG) sensor written by high-frequency CO2 laser pulses is demonstrated for simultaneous measurement of transverse load and temperature. Such a sensor could solve the cross-sensitivity problem between transverse load and temperature due to the unique features of the LPFG, i. e. the load-sensitivity of the LPFG against the resonant wavelength shift strongly depends on loaded orientation. Within the circular position 0°～180°, there are one orientation which is the most load-sensitive, corresponding to the resonant wavelength“red”shift and another orientation which is the most load-sensitive, corresponding to the resonant wavelength“blue”shift, in particular, there are two special orientations, which are the most load-insensitive.
