旋转式粘度计的单片机控制

介绍一种旋转式粘度计的单片机控制测量方法。作者采用ＣＴＣ计数法集外筒测速、调速和测内筒扭矩于一体，既可分档测量，也可连续测量，满足各种农产品、食品流变试验的要求。单片机ＣＰＵ取代人工自动进行数据处理，实现粘度测量和分析的微型计算机化，具有使用方便、成本低、功能全的特点。

THE CHIP MICROCOMPUTER CONTROL OF THE ROTATIONAL VISCOMETER

The viscocity is a main rheological coefficient of many agricultural products and foods.A new method of the chip microcomputer control in the rotational viscometer was expounded.The CTC counting method was used to measure and adjust the speed of outer tube and measure the torsional moment of inner tube at the same time.The torsional moment of inner tube can be measured not only when outer tube rotates at different grade velocity but also when the velocity of outer tube is varied continually.The CPU of microcomputer deal with data processing automatically instead of manual work.The measurement and analysis of viscocity were completed computernizationally.This chip microcomputer control was applied in rheological experiment of foods and showed its advantages of good function,low cost and convenient operation.
