1980年10月—11月望峰岗选煤厂在兰州化学工业工司自动化研究所的帮助下,进行了FGDR—2型γ射线密度计检测煤泥水浓度的工业性试验。试验取得了满意的结果。自去年秋天以来已使用将近一年了,现将该密度计的结构性能及试验结果介绍如下。FGDR—2型γ射线密度计属非接触式密度计,由放射源铯Cs~(187)、探头、电路主体和调校机构四大部分组成,还配有一台XWC—200型电子自动记录仪。其
October 1980-November Wangfenggang Coal Preparation Plant in Lanzhou Chemical Industry Division with the help of the Institute of Automation, conducted a FGDR-2 γ-ray density meter test slurry concentration of industrial tests. The test has achieved satisfactory results. It has been in use for almost a year since it was last fall. The structural performance and test results of this densitometer are described below. FGDR-2 type gamma ray densitometer is a non-contact density meter, which is composed of radioactive source cesium Cs ~ (187), probe, circuit main body and adjustment mechanism. It is also equipped with a XWC-200 electronic automatic recorder . its
