一个动态不连续物料的在线中子测水系统

An on-line neutron moisture measuring system for discontinuous process materials

介绍了一个用γ密度计作密度补偿的用于测量在传送带上处于运动状态的一块一块不连续物料中水分的在线中子测水系统．来自中子、γ射线及电子秤探测器的实测数据均通过一个计数卡输入到ＰＣ机中，由微机作数据处理、记录和显示，并用表格和图形给出各时刻的瞬时湿度及某段时间间隔内通过传送带的物料的总重量、干料量和水分量。

An on-line neutron moisture measuring system for discontinuous moving materials(such as ore) mounted over a conveyor is described.A gamma density gauge was used to provide density-corrected direct readout of water content.in terms of weight percentage.Three groups of measuring signals coming from a slow neutron detector,a garnma ray detector and an electronic weigh system were together fed into a PC computer through a count card to realize data processing,recording and displaying.The prompt and average moisture content, as well as total material,pure dry material and water passing the measuring point at a certain time interval can be plotted or tabulated.
