The sensor is determined for static, as well as dynamic measurements of tensile strengths of individual yarns. It is characterized by a large measuring range, universal use and high dynamic parameters for the most exacting and demanding measurements.
The sensor of yarn tensile strengths is supplied with the range of 0 – 300 cN or 0 – 1000 cN. A yarn guide/finger is made of a thin-walled sapphire tube; deformations of measuring little beams are sensed by high quality semiconductor strain gauges. The sensor is equipped with the compensation of temperature and the compensation of thread sapphire finger heating due to the friction of the passing thread.
