摘要
介绍了一种基于黑体腔辐射原理的蓝宝石光纤瞬态高温传感器,深入分析了传感器的工作原理,详细介绍了传感器的黑体腔设计、壳体结构以及K值的标定;抗冲击压力测试是蓝宝石光纤瞬态高温传感器研究过程中的一个重要环节,在抗冲击测试中,采用锤击的方式模拟冲击环境,在锤击式压力发生器对该温度传感器探头施加一定压力的同时,利用激光器对温度传感器的探头加热;实验结果表明:在3 000℃左右的高温环境下,该传感器其抗压能力为50MPa以上。
Discuss sapphire fiber transient high temperature sensor which is based on blackbody radiation theory, explore its working principle, and describe the design of blackbody, the shell structure, and the calibration of K value are introduced in detail. The impact pressure test is an important part in the course of the study of the sapphire fiber transient high temperature sensor. Shock environment was simulated by means of hammering in the impact property test. Pressure was applied to the temperature sensor probe by hammering pressure generator, use laser to heat up the probe. The result showed that the sensor could resist the pressure over 50MPa under a high temperature condition （around 3000℃ ）.
