本实施例中，所述第三导纱孔8通过第一连接件10与所述电容位移传感器11的可移动极板的上端相连接。In this embodiment, the third yarn guide hole 8 is connected to the upper end of the movable plate of the capacitive displacement sensor 11 through the first connecting member 10 .
本实施例中，所述电容位移传感器11的可移动极板的下端通过第二连接件17与所述轻质弹簧12的上端相连接。In this embodiment, the lower end of the movable plate of the capacitive displacement sensor 11 is connected to the upper end of the light spring 12 through the second connecting piece 17 .
本实施例中，所述分纱器6下部设有分纱器位移传感器5。In this embodiment, a yarn divider displacement sensor 5 is provided at the lower part of the yarn divider 6 .

经测定，纱线张力适度时，=，即为第三导纱孔8的初始位置，电容位移传感器11的可移动极板位置为零初始位置，弹簧受压缩力，初始值为；It has been determined that when the yarn tension is moderate, = , which is the initial position of the third yarn guide hole 8, the position of the movable plate of the capacitive displacement sensor 11 is zero initial position, the spring is compressed, and the initial value is ;
纱线张力增大，第三导纱孔8位置上移，第一连接件10带动电容位移传感器11的可移动极板上移，轻质弹簧12受压缩力；As the yarn tension increases, the position of the third yarn guide hole 8 moves upward, the first connecting piece 10 drives the movable plate of the capacitive displacement sensor 11 to move, and the light spring 12 is compressed;

Then calculate the tension force of light spring 12 as , which is the longitudinal elasticity of the yarn . From inverse trigonometric functions = , and the yarn tension obtained from the principle of Newtonian mechanics = .
以上计算均由微处理器完成，纱线张力适度，测定此时电容位移传感器11的可移动极板的位移量，得出，以及轻质弹簧12初始弹力，其中为弹簧初始变形量。AD转换后所得值为位移量初始值，=0。The above calculations are all completed by the microprocessor, and the yarn tension is moderate. Measure the displacement of the movable pole plate of the capacitive displacement sensor 11 at this time, and draw , and the initial spring force of the lightweight spring 12 ,in is the initial deformation of the spring. The value obtained after AD conversion is the initial value of displacement, =0.
纱线张力增大，AD转换所得值大于初始值，；纱线张力减小，AD转换所得值小于初始值，。电容位移传感器11所得电信号经差动放大滤波，另设有温度补偿电阻，能很好抑制干扰，在此不再赘述。The yarn tension increases, and the value obtained by AD conversion is greater than the initial value, ; Yarn tension decreases, the value obtained by AD conversion is smaller than the initial value, . The electrical signal obtained by the capacitive displacement sensor 11 is filtered through differential amplification, and a temperature compensation resistor is also provided, which can well suppress interference, and will not be repeated here.
