自从本刊1977年第5期发表《简易插入式光电高温计在高温盐浴炉中的应用》一文后,不少同志来函了解简易插入式光电高温计(以下称仪表)的原理和制作等问题。为此,本文进一步作如下补充。一、仪表的制作简易插入式光电高温计是利用全辐射感温器的壳体及光路,以硅光电池作感温元件改装而成。感温镜头前装有导光管插入高温盐浴炉中,以电子电位差计为二次仪表。图1为该仪 Since the publication of the fifth issue of 1977, “Application of a simple plug-in photoelectric pyrometer in a high-temperature salt bath furnace”, many comrades have come to understand the principles and fabrication of the simple plug-in photoelectric pyrometer (hereinafter referred to as the meter) . To this end, this article is further supplemented as follows. First, the instrument production Simple plug-in photoelectric pyrometer is the use of full radiation temperature sensor housing and optical path to silicon photovoltaic cells for temperature-sensing components converted from. Temperature sensor with a light guide tube inserted into the high temperature salt bath furnace to electronic potential difference meter as a secondary instrument. Figure 1 for the instrument
