| Abstract: | Adopting the design of spoke-type sensing structure, the sensing head is composed of two Bragg gratings, which have different wavelengths and are bonded to the middle of two symmetrical spoke side surfaces with same angles along the direction of the spoke neutral axis. Using the characteristic of fiber grating absolate code, the spoke-type fiber grating sensor of measuring force with temperature active compensation is designed and manufactured. The theoretical analysis and experimental results indicate that this sensor has the function of temperature active compensation, it can be used in high precision sensing and measuring of pressure and pull, the maximal force measurment value is up 3 kN and the temperature active compensation range is between -20 ℃ and 75 ℃. |
