Thermocouple surface temperature sensor recording thermocouple pyrometer 热电偶表面温度传感器
The temperature of oxyacetylene flame was simultaneously measured by the pyrometer and a thermocouple. And the measurement error of the single-wavelength pyrometer is only 6.2%. 由单色高温计与热电偶测温对比实验可知,在单色测温中爆炸产物可近似看作黑体处理,其误差率为6.2%。
The thermocouple, the secondary instruments and suction system consist of a complete set of suction thermocouple pyrometer, which could effectively reduce the effect of radiation in furnace and exactly and quantitatively measure the temperature of defined point in furnace. 它与二次仪表及抽气系统组成整套的抽气热电偶高温计,能有效的减少炉膛辐射的影响,可以准确的定量测量炉膛内部确定点的温度。
At present, Pt-Rh thermocouple and optical fiber pyrometer are in common use. 目前常用的温度传感器为铂铑金属热电偶和光纤型高温计。
