Abstract
According to the theory of thermal radiation, an improved colorimetric radiation temperature measurement system was established based on the existing one what are used in industry. At the optimal operating temperature, the calibration experiments were conducted in a high temperature blackbody furnace. The operating parameters were determined, and the accuracy of the colorimetric thermometer applied to measuring transient high temperature was verified. The temperature response of large-equivalent fuel air explosion field was detected by using the colorimetric temperature sensor. The analyzed results show that the temperature response of explosion center appears a multimodal structure, the maximum temperature of the cloud was achieved at 2 m away from the detonation center, and the detonation area near the boundary of 4~8 m is at a continuous, stable and high temperature.
