摘要： 实验室现用落球法液体黏度测量仪一般配备了激光测量和单片机数据处理,但由于其激光测量部分经常捕捉不到落球,使用起来极不方便.本文以很低的成本对其进行改造,使仪器的捕捉率达到90%以上,满足了教学和生产实际的需要.
关键词: 落球法黏度测量仪, 拓展光源, 接收电路, 捕捉率
Abstract: The accurate measurement of the liquid viscosity is quite important in the teaching of physics and industrial application. However, there is an obvious drawback in the traditional measuring skill. We can not catch the iron ball so easily. In this paper, we design a new kind of apparatus at a low cost which can improve the capturing rate up to 90 percent. This new designed instrument works quite well when it is applied to the measurement of the liquid viscosity.
Key words: measurement of liquid viscosity with falling-ball method, broadening light source, receiving circuit, capturing rate
