A, use:
Determination of single fiber breaking strength, elongation, tensile strength, elongation constant load, constant elongation strength, elongation at break time and a strong curve.
B, principle structure
Instrument testing principle of constant elongation (CRE). Instrument by the host, a computer, printer and compressed air composed of four parts. Force sensors measure strength, elongation measuring grating encoder. WindowsXP operating system, LCD display data and the tensile curves.
C, Product Features
1, high precision: High-precision sensor technology to produce the United States, and with the software is divided into third gear (25, 50, 100cN).
2, reliable, stable, low failure rate; selection of imported drive speed and international advanced technology of rare earth motors.
3, wide speed range, high precision: 0.2 ~ 200mm / min, speed ratio up to 1000 times, accuracy ± 2%, ± 5% accuracy higher than the tensile tester requirements at the national level.
4, convenient and reliable clamping methods; using pneumatic clamping, the clamping force constant, with soft and hard with clips to prevent slipping, crush sample, while avoiding hand-holding, tight crush sample, too loose slipping the impact of data correctly.
5, powerful, easy to upgrade; can not only breaking - elongation test, but also set a strong, constant elongation test, according to the special requirements of users, preparation of software to reach specific requirements.
