摘　　要：基于目前传统方法测量液体粘滞系数存在重复率低、误差大、测量范围小等问题,采用单片机、金属传感器对现有液体粘滞系数测量装置进行了改进。通过金属传感器感应金属小球,配合单片机计时并显示时间结果,应用计算机计算液体粘滞系数。实验结果表明,改进后的测量装置测量过程直观、准确,测量计算所得粘滞系数误差较小,且适用于测量不透明液体粘滞系数,拓宽了液体的检测范围。Based on the existing problems in the traditional measurement method of liquid viscosity coefficient,like low repetition rate,large error and small measurement range,it adopts single chip microcomputer and metal sensor to improve the existing device.The metal sensor senses the metal ball,cooperates with the single chip microcomputer to time and display the time results,and the computer is used to calculate the liquid viscosity coefficient.The experimental results show that the measurement process of the improved measuring device is intuitive and accurate,the error of the viscosity coefficient measured and calculated is small,and it is suitable for measuring the viscosity coefficient of opaque liquid,which widens the detection range of liquid.
