基于有机消融涂层GT-401的蓝宝石光纤瞬态高温
传感器的黑体腔研究
摘要:温度在科研和生产中是一个十分重要的物理量,当前许多研究对象需要测量的是幅值高、变化快的瞬态高温。黑体腔探头的设计是蓝宝石光纤高温传感器研制的关键,探头的结构、材料及镀膜工艺决定着传感器的测温上限、动态响应以及使用寿命,也决定着探头本身的热辐射特性,从而影响到传感器的测温精度、重复性与稳定性。本文使用将耐高温黑体腔与光纤辐射测温技术相结合的接触—非接触测温的方法,通过在传感器探头用浸渍法涂敷GT-401涂料,提高了蓝宝石光纤瞬态高温传感器的感应温度,而且使测量更准确,快速,以期达到预期的目标:使蓝宝石光纤瞬态高温传感器能抗高温2500℃无镀膜剥落,且时间常数<100ms。

Transient high-temperature sapphire fiber anic ablation coatings GT-401Sensor of the blackbody cavity study
Abstract: The temperature in the research and production is a very important physical quantities, many of the current study measured the amplitude, fast changes of transient high temperature. Blackbody cavity probe design is the key to development of sapphire fiber-optic high temperature sensor, the structure, material and coating process of the probe determines the maximum temperature of the sensor, the dynamic response and service life, but also determines the thermal radiation characteristics of the probe itself, which affects the sensor temperature measurement accuracy, repeatability and stability. This article uses bination of high temperature blackbody cavity with optical radiation thermometry contacts - non-contact temperature measurement method, the sensor probe GT-401 coating, impregnation coating, sapphire optical transient high temperature sensor has a temperature measurement more accurate, fast, in order to achieve the desired objectives: sapphire optical transient high temperature sensor can be resistant to high temperatures of 2500 ° C coating spalling, and the time constant of <100ms.
