A High-precision Method of Tension Measurement for Small-sized Fiber

A high-precision approach of tension measurement for small-sized fiber is proposed to overcome the defects of existing methods. Multithread and high-precision timing techniques are used to produce pulses for driving stepping motor to stretch fiber, Strain gauge and BP neural network are introduced to measure fiber tension. The stretching process and measuring operation are automatically controlled by the measurement software, which makes it fairly easy to measure the tension of leather fiber and pulping fiber which are thin and of small size. This method is characterized by convenient operation, accurate measurement and high degrees of visualization.
