A laser negative step temperature generator for on-site dynamic calibration of temperature sensor was set up. The experimental data processing method of sensor dynamic calibration was used to study the dynamic calibration and performance improvement of BTS-100 PN junction temperature sensor. The experimental results show that the above calibration method has the characteristics of non-intervention, strong field and high calibration accuracy, and has broad application prospects.
