光谱比高温计比一般的辐射高温计少受诸如中间介质辐射的吸收和对象辐射能力变化这一因素的影响。本文即介绍了苏联列宁热工仪表科学生产联合企业近年来研制成功和成批试生产的一套光谱比自动高温计的有关技术特性、结构框图及工作方式等。
The spectral ratio pyrometer is less affected by factors such as the absorption of the intermediate medium radiation and the change of the radiation ability of the object than the general radiation pyrometer. This article describes the Soviet Union Lenin thermal instrumentation scientific joint ventures in recent years, the successful development and mass production of a set of spectral than the automatic pyrometer of the technical characteristics, block diagram and working methods.
