1/2/°C between 300 °C and 1750 °C, and it can work stably for more than 10 h. The sensor is calibrated in the metrology institute, where a maximum quoted error of 0.84% within a range between 900 °C and 1600 °C is proven. Compared with the traditional high-temperature measurement method, the sensor has the advantages of compact structure, antielectromagnetic interference, large measuring range, and good linearity, which can be widely used in the sensing and measurement of extreme high-temperature environments, such as aeroengine tail injection temperature monitoring and combustion chamber temperature monitoring of aeroengine simulation test benches.">
