Automatic zero-adjusting Yarn Testing Equipment CT200 Yarn Evenness Tester

Automatic zero-adjusting Yarn Testing Equipment CT200 Yarn Evenness Tester

Description:

Evenness Tester is a kind of universal high-performance textile lab instrument.

It is used for testing yarn unevenness and hairiness variety, which is suitable for cotton, wool, silk, flax, chemical short fiber spinning and blended yarn.

It is very important to improve and guarantee yarn quality.

It consists of detector, host processor (including monitor, keyboard, and mouse), printer, and yarn bracket.

 Host processor adopts PIV industrial control computer, monitor software bases on Windows platform, Chinese graphic interface, good system integration and high stability.
It can test CV% value, U% value, H value, SH value and twelve levels faults in real time.
It has various graphic indices, such as variation-length curve, unevenness curve, spectrogram, linear density-frequency distribution, etc of yarn and hairiness, which are convenient to evaluate yarn quality.
It has fine continuous spectrum and 340 channels, which are beneficial for user to analyze textile technology trouble location accurately.
Transmission system adopts imported servo system, low noise and high reliability.
Automatic zero-adjusting function improves testing efficiency, operation is simpler.
Statistical analysis system can supply annual, quarterly, monthly, daily report of specific variety testing data and statistical distribution graph of regular testing indices, which are beneficial to observe mid-long-term variation of testing indices.
Electromagnetic tensioner makes tension adjusting more convenient and reliable.
Expert system can help user analyze textile technology trouble, compare with USTER bulletin and evaluate spinning level.
It can store uneven curve and supply for users to analyze more in detail.
Automatic yarn shifting function can make trasmission roller working life longer.
Data is stored by time and variety. File system supplies various testing information, and it’s more convenient for user to check.
