| Abstract: | The amplifying circuit consisting of semiconductor strain gauges and precision instrument amplifier was introduced to convert a milivolt-level voltage into the one within 5V;through calibrating the fiber tensile measurement,the corresponding relationship between fiber tension and voltage was determined and the value of the fiber tensile was drawn,and the introduced step motor solved the problem concerning the precision,micro-step and position of fiber tension.Through PC control data acquisition card and reading the value into the memory,the fiber tensile measurement can be realized. |
