Scope of application: YG086C yarn length measuring instrument is used to shake a certain length of yarn or chemical fiber filament, and use the electronic balance to weigh the weight, which is used to calculate the linear density of yarn or chemical fiber filament (tex, points Tex dtex, denier D, yarn count and other indicators). Definition of yarn linear density: ①. tex: refers to the weight of a 1000-meter-long yarn in grams at a given moisture regain. ②. Dtex dtex: refers to the weight of 10,000 meters of fiber or yarn in grams at a constant moisture regain. ③. Denier D: refers to the mass grams of a 9000m-long fiber at a given moisture regain.

Instrument characteristics: 1. Transmission mechanism: The spring automatic fastening mechanism is adopted to automatically adjust the position of the motor to ensure the accurate stop of the yarn frame. 2. Counting part: It adopts mechanical dial input and digital block display output to achieve intuitiveness, improve the accuracy and reliability of the input part, and extend the service life of the counter. 3. Control part: single-chip control, stable start and stop, low operating noise, accurate lap counting, and no lap phenomenon. 4. Adjustment part: adopt soft start method to extend the use and life of the motor. The controllable KC05 is used as the main component of the high-speed part to reduce the number of relays and enhance the stability and anti-interference of the machine. With automatic positioning function, the last lap is controlled by program curing. technical parameter: 1.
