The purpose of this paper is to study the calibration method of new intelligent bearing applied to NiCr/NiSi film thermocouple. Firstly, the basic principle and characteristics of NiCr/NiSi film thermocouple and intelligent bearing are introduced, and then the design and realization process of intelligent bearing are elaborated, including material selection, structural design, manufacturing process and so on. Then, this paper puts forward the calibration method of intelligent bearing, and verifies its effectiveness through experiments. The experimental results show that the Seebeck coefficient of NiCr/NiSi thin film thermocouple new intelligent bearing is 41.00 μV/°C, and the Seebeck coefficient of standard K thermocouple is 41.20 μV/°C. The new intelligent bearing has high sensitivity and stability, and can achieve fast response and accurate measurement. Finally, this paper summarizes the research results, and looks forward to the future research direction.
