The sensor adopts the FBG, no current passes through the optical fiber, and no electrical connection is needed; the force sensing system is not disturbed by electric noise and electromagnetic interference; the sensing element has small size and light weight, high precision, zero drift, wide frequency response and good high-temperature performance.
