在化学气相沉积纤维的过程中,需要测量温度,本文专为解决这一动态小目标温度的测量而开展的。沉积纤维的直径在20～100μm之间变化;沉积过程中纤维以每小时200m的速度行进,并在行进的垂直方向作不规则振动;沉积系统要求密封,因而给测温带来了较大的困难。在这种情况下,接触式测温是无能为力的,非接触式中的一般亮度法、全辐射法也不能解决问题。由于光电比色法的示值与测量距离、辐射表面的大小及光学系统关系不大,故采用了此法,同时在光学系统和电路上采取了一些必要的措施,研制了纤维测温仪。测量范围:1000～1400℃;精度:±1％(按显示仪表上限计算);反应速度:不大于1秒;测量距离:120mm。
In the process of chemical vapor deposition of fiber, the need to measure the temperature, this article specifically to address the dynamic small target temperature measurement carried out. The diameter of the deposited fibers varies between 20 and 100 μm; fibers travel at a speed of 200 m / h during deposition and are irregularly vibrated in the vertical direction of travel; the deposition system requires sealing and therefore gives rise to a large difficult. In this case, contact temperature measurement is powerless, non-contact general brightness method, the whole radiation method can not solve the problem. Because of the photoelectric colorimetric method of indication and measurement distance, the size of the radiation surface and the optical system is not, so this method is adopted, while taking some necessary measures in the optical system and circuit, developed a fiber thermometer. Measuring range: 1000 ~ 1400 ℃; Accuracy: ± 1% (calculated according to the upper limit of the display instrument); reaction rate: not more than 1 second; measuring distance: 120mm.
