A new inclination sensor based on embedded fiber gratings and carbon fiber equi-strength beams is proposed. The measuring principle and the manufacture methods of this sensor are first introduced. Then this sensor is fully tested. The research results show that, within a measurement range of ±30°, the sensor possesses a sensitivity of 49.73 pm/(°), a measurement accuracy of 0.101°, a repeatability error of 0.62%, and a fitting linear correlation coefficient of 0.99992. Furthermore, the creep resistance and the good temperature compensating abilities are good. The requirement of long-term inclination monitoring under complex electric environments is met.
