Fiber grating ice pressure sensor

The utility model provides a fiber grating ice pressure sensor, which comprises an outer casing, supporting bases arranged on both ends in the outer casing, and an equal strength perception beam installed in the middle of the outer casing. One end of the equal strength perception beam is fixed on a supporting base and the other end is a cantilever end. The optical fiber grating sensor is glued on the equal strength perception beam. The equal strength perception beam is provided with an elastic beam. Both ends of the elastic beam are supported on the supporting base and one of the both ends is fixed with the supporting base and the other end is not fixed. The mid-point of the elastic beam is connected with the cantilever end of the equal strength perception beam. The utility model also comprises a reinforcing beam. The beam plate of the reinforcing beam is positioned outside the outer casing and both ends extend into the outer casing and contact the elastic beam. The utility model has the advantages of temperature self-compensation, monitoring load independence of the application point, high precision, favorable durability, low cost, simple implementation, etc.
