Yarn Evenness Tester

Model No.

YG139C-J Filament Yarn Evenness Tester

Application: 

YG139C-J Yarn Evenness Tester is used to inspect and analyze the mass variation in filament yarns with mechanical twisting technology and the idea of modulus design. Faults on various devices or processes used in the procedure of manufacturing filament yarns can be tracked or diagnosed by analyzing the curve of wavelength-spectrogram, unevenness curve, and variance length and statistic data.

Filament Yarn Evenness Tester

Features:

• Specialized ×24 capacitance detector for inspecting filament yarns with high precision;

• Adopt an industrial processor as host processor, equipped with specialized signal-processing module and well-adapted to environment;

• Block-designed whole structure and software system with excellent expansibility;

• With self-designed twisting device;

• Automatic yarn feeder without extra tools;

• High-speed servo system made in Switzerland for twisting;

• Visualized operation of steplessly adjusting the twisting speed, accurate and intuitive, can automatically save twisting parameters of varieties, easy to operate;

• Completely-digital speed adjusting system, automatic roller's movement and extended roller's service life;

• Be able to store unevenness curves, shrink or enlarge them according to several scales;

• Be able to directly measure the length of any point on any unevenness curve by using the unique electronic ruler designed by our company, which is convenient to correctly analyze faults on devices or processes with the help of spectrogram;

• Synchronously output conventional test results and those of various inhibition, half-inhibition and segments; 

•  Test results are stored in a database, so the user can classify, analyze and rapidly retrieve them;

• Be able to insert any test without affecting other tests;

• The technology of data protection and restoration can effectively protect various data reports stored in computer and rapidly solve any breakdown caused by the software or hardware;  Be able be equipped with automatic yarn feeder to realize automatic test and to improve the testing efficiency.
