Digital Displaying Tensile and Elongation Testing Machine for Yarn
It is applicable for wide range of material for tension, compression, bending, shearing and low cycle test. Suitable for metal, rubber, plastic, spring, textile, and components testing. It is widely used in the corresponding industries, research and development, test institutes and training centers etc.
ASTM, ISO, DIN, GB and other international standards.
3.Main Technical Parameters:
4. Main Unit Feature:
4.1 Adopt single column structure, lower for tensile, upper for compression, double space. The beam is step less lifting, light but rigid.
4.2 Adopting ball screw drive, realize no clearance transmission,make sure the precision control of the test force and deformation speed.
4.3 The photoelectric encoder is the displacement sensor, with high resolution, strong anti-interference ability.
4.4 The shield plate with limit mechanism used to control the beam moving range, in order to avoid sensor damaged due to the moving distance is too large.
4.5 The table, moving beams is made of high quality precision machining steel plate , not only reduce the vibration generated by specimen fracture, but also improve the stiffness.
4.6 The motor tail is upwards, above the work surface, this design makes the main unit lower space narrowing, the whole machine is more coordinating, and more easy to spread out the heat generated by the motor rotation, extend electrical components life.
4.7 Three columns of mandatory orientation, make the main unit rigidity much improved, to further ensure the repeatability of measurement.
4.8 Adopt bolt type grip installation, make the grip replace easier.
5. Function Feature:
5.1 Automatic calibration: system can automatically realize the accuracy of the calibration value.
5.2 After the sample broken, automatic stop.
5.3 Automatic display: During the whole testing process, the LCD real-time display the testing force,peak value, displacement, testing speed and testing force-time curve,testing force-displacement curve.
5.4 Automatic return: beam automatic return to initial position when testing finished.
5.5 Breakage judgment: sample after fracture,beam automatic stop moving.
5.6 Limiting protection: Program control and Mechanical limiting protection.
5.7 Overload protection: When more than 3 to 5% of the rated load device automatically stop working.
5.8 Automatic calculation: automatic calculation area after input sample diameter (round)Width, thickness(flat), sample gauge ect.
