Wells-Brookfield锥板流变仪是一个精密的扭矩计，以离散的转速驱动。扭矩测量系统由一个校准过的铍铜弹簧组成，弹簧将驱动机构连接到一个旋转的锥转子上，感应锥转子和固定平板之间存在的样品流体引起的旋转阻力、�/span></p><p><span> 锥转子的旋转阻力产生的扭矩与流体中的剪切应力成正比。该读数可从预先计算的量程图转换�?*厘泊单位(mPa��s)。另外，粘度可以从已知的圆锥几何常数、旋转速率和应力相关的扭矩中计算出来、�/span></p><p><span> 正确的锥转子和平板的相对位置可通过一个简单的机械程序获得，不需要外部仪表或辅助设备、�/span><span>固定平板构成可拆卸的样品杯底部，注入0.5 ml�?.0
