摘　　要：针对目前国内缺乏1200℃以上长时间超高温气体环境下有效的温度测试手段,基于超声脉冲穿透测温原理,通过设计均匀分布的平面八元圆环温度传感器阵列,成功研制出一种高效的温度场检测系统。依据波速V与气体温度T之间的经验函数,利用高温实验获得了各传感器性能数据。实验结果表明:该系统在1200℃高温环境下测量精度达到了97.98%,重复性95.52%以上,响应时间毫秒(ms)级别,符合设计要求。Aiming at the current lack of effective temperature testing means for long-time ultra-high temperature gas environment above 1200℃in China,based on the principle of ultrasonic pulse penetration temperature measurement,and by designing an uniformly distributed array of planar eight-element circular temperature sensors,an efficient temperature field detection system is successfully developed.According to the empirical function between the wave velocity V and the gas temperature T,the performance data of each sensor are obtained through high temperature experiments.The experimental results show that the system achieves a measurement precision of 97.98%,a repeatability of more than 95.52%,and a response time of milliseconds level at a high temperature of 1200℃,which meets the design requirements.
