Product features:
1. Four column full rigid frame structure, high precision, anti direction finding, hydraulic automatic clamping.
2. Two way oil cylinder, good sealing performance and high precision. The long stroke two-way oil cylinder can meet the tensile requirements of samples with different length specifications. The vibration of the samples after fracture is small and the energy absorption and shock absorption are good.
3. High precision load sensor (better than ± 0.5%), strong overload bearing capacity, reasonable structure, unaffected by temperature, high measurement accuracy, repeatability of indication, good output linearity, high stability.
4. The oil cylinder is installed on top, which conforms to the working height and test space of the ergonomic principle, reduces the labor intensity and makes the operation more convenient.
5. Adopt radial piston oil pump.
6. Adopt AC servo control system, mute load, high control precision.
7. Semi closed jaw, high rigidity, to minimize sample slip, high precision.
8. The paint of the whole machine adopts spray molding technology, which is wear-resistant, dirt resistant and easy to clean.
9. The networked measurement and control system has the functions of gain adjustment, zero fullness, etc. to ensure the smooth operation and accurate measurement of the machine.
10. The automatic control system adopts computer and electro-hydraulic servo system for control loading and full automatic control.
11. The main components of the hydraulic system are imported parts, which make the loading accuracy of the testing machine higher, noise lower, durability better, and enhance the stability of the machine.
12. Equipped with the current advanced industrial grade embedded tablet computer, it can withstand the voltage range of 85-250v, with stronger anti-interference performance.
13. The computer adopts touch screen technology, which can be used for touch operation or keyboard operation. It is more ergonomic and convenient to operate.
14. By using Windows system control software, the elastic modulus E, upper yield strength Reh, lower yield strength rel, specified non proportional extension strength RT, yield point elongation and other technical parameters can be obtained automatically.
15. Complete test report and test curve can be automatically printed.
16. It has LAN networking function and remote database seamless connection function.
