根据石油混合物液体的荧光特性，研制了油砂含油量测定仪。介绍了测量原理、光路系统和仪器总体结构。用光电信增管将反映含油量的荧光强度转变成电参量，利用单片机对数据进行分析处理。说明了油砂含油量单位和标准样品制作方法。给出了仪器实际测试结果。 According to the fluorescence characteristics of the oil mixture liquid, oil content tester has been developed. The principle of measurement, the optical system and the overall structure of the instrument are introduced. With optical telecom tube will reflect the fluorescence intensity of oil into electrical parameters, the use of single-chip data analysis and processing. Describe the oil sands unit and standard sample production methods. The actual test results of the instrument are given.
