一、前言光电测沙仪是快速测定含沙量的一种仪器,一般传统袭用的光电测沙仪是取样式的。在进行多点测量时不仅需要增添许多取样孔及取样设备,而且当进行同步测量时尤感麻烦;因无法获得连续的含沙量的变化过程,使试验过程的观测、控制、确定边界加沙量等均感不便。为此,我们研制了浸入式的探头,即将微型的光电测沙探头直接置于水中。这样,配用自动记录仪后便能连续记录含沙量的垂线分布、横断面分布以及纵向 First, the foreword Optoelectronic sand detector is a rapid determination of sediment concentration of an instrument, the general attack on the use of the photoelectric sand detector is to take style. In the multi-point measurement, not only need to add many sampling holes and sampling equipment, and when the simultaneous measurement is particularly troublesome; can not get continuous changes in sediment concentration, so that the process of observation and control of the process, to determine the boundary Gaza So inconvenient. To this end, we developed a submerged probe, which is about to put a miniature photoelectric probe into the water. In this way, with the automatic recorder can record the vertical sediment concentration distribution, cross-sectional distribution and vertical
