generation high efficiency single yarn tension tester which adopts pneumatic technology, it is used to test yarn breaking strength, breaking elongation rate, breaking intensity etc indices. Its function and performance all accord with national standard GB/T3916-1997. It has advantages of high testing efficiency, accurate testing data, reliable performance, easy operation, convenient service, etc.MAIN FEATURESIts testing efficiency is high which is 20~30% higher than common single yarn tension tester in the market.It adopts pneumatic holding device, soft holding motion is not easy to damage yarn.It adopts computer control, Chinese interface, easy operation, convenient, and manual testing function.It can display forcing-extending curve (F-E curve) in real time, and can process testing result graphically.Yarn creel can install 20 tubes of yarn at once, install continuous test of 40 tubes at twice, and each tube can test 100 groups of data.It can automatically choose best measure range, automatically or manually reject unusual data.Motor driver system all adopts subdivision technology, high reliability, is high, smooth running, low noise.Sampling roller adopts antistatic and anti-winding device, reduce winding yarn.SPECIFICATIONTesting principle constant rate of extension (CRE)Sample length 500mm±1mmForce testing range 0~5000cN, sensitivity＜1.5cNElongation range 0~250mm, error＜±1mmTension speed range 50mm/min~5000mm/minPre-tension range 2cN~150cNInterval sampling length 0~100mTesting contents 1~100 time/tube, 1~40 tube/group, total numbers ≤2000Output index breaking strength, breaking elongation rate, breaking time, breaking work, breaking intensity, tension CV value, elongation CV value, max tension and elongation value, min tension and elongation value, minimal quintic average, fiducial interval, spline graph, splattering graph, histogram and breaking strength correction, etc.Power supply voltage AC220V±10%frequency 50Hz±5%power consumption ≤400WEnvironment temperature 20℃±10℃humidity 60±15％RHCOMPOSITIONIt is composed of tester, printer, work table, and yarn creel.
