A novel functional-type high integration polarization interference fiber temperature sensor based on 45° tilted fiber Bragg grating in-fiber polarizer (TFBG-PIF-TS) is proposed. The accuracy, resolution, stability, linearity and sensitivity of the prototype are tested and compared with PT100, 18B20 as well as polarizing plate based polarization interferometric fiber temperature sensor (PP-PIF-TS). The feasibility of the scheme in the transformer winding temperature monitoring is verified. The results show that the accuracy and resolution of TFBG-PIF-TS reach ±0.1 °C and 0.01 °C respectively, which has higher resolution, better integration and reliability, and has simple structure, strong anti-vibration and anti-electromagnetic interference abilities. Therefore, the proposed scheme can meet the needs of high voltage, strong magnetic field and other passive precise temperature measurement occasions.
