针对瞬态高温的测量难题，采用辐射式测温技术和接触式测温技术有机结合的方法，设计了由黑体辐射温度敏感体、圆柱状高强度金属外壳以及壳内信号调理电路构成的瞬态高温测量装置。通过对感温薄膜特殊材料的恰当选取以及整体结构的合理设计，并利用ANSYS软件对其黑体感温薄膜进行了瞬态高温热传导分析。分析表明，施加的温度载荷为2000℃、2500℃、3000℃时，此温度传感器响应时间分别为487．001μs、545．001μs、590．001μs ，能够克服传统瞬态温度传感器体积大、响应慢、安装不方便以及易受恶劣环境因素影响等不足，在测温技术领域具有良好的应用价值。

Against the difficult problem of the transient temperature measurement ,by using the radiation thermometry technology and contact thermometry technology combined method ,w e designed a transient high temperature measuring device w hich consisted of the black‐body radi‐ation temperature sensitive body ,the cylindrical metal housing of high strength and the signal conditioning circuit in the housing .Though the proper selection of thermal sensing thin film special material and the rational design of the overall structure ,as well as using ANSYS software ,we analyzed the transient high temperature heat conduction of the black‐body temperature thin film . Analysis shows that when temperature load of 2 000 ℃ ,2 500 ℃ ,3 000 ℃ applied ,the tem‐perature sensor response time was 487 .001 μs ,545 .001 μs ,590 .001 μs ,respectively .This device can overcome the traditional transient temperature sensor shortcoming of bulky ,slow response ,inconvenience to install and susceptibility to harsh environment factors and so on .It has a good application value in the field of thermometry technology .
