20kn Fiber Digital Universal Tensile Strength Testing Machine

1. Application
This testing machines is equipped with computer, printer, and general test software, to give an accurate determination of metal the material tensile strength, yield strength, the provisions of non-proportional extension strength, elongation, elastic modulus mechanical properties. Test results can print (force - displacement, force - deformation, stress - displacement, stress - deformation, force - time distortion - time) six kinds of curves and related test data, with the software self-test function that can self-diagnose problems. It is ideal testing equipment for the industrial and mining enterprises, scientific research units, universities, engineering quality supervision station. They are perfect testing instrument project quality testing section, universities and colleges, research institution and industrial and mining. 

2. Test capability of machine and relevant Standard:
ASTM E8 - 16 Standard Test Methods for Tension Testing of Metallic Materials
ISO 6892-1 Materials --tensile testing
ASTM A370-05 Standard Test Methods and Definitions for Mechanical Testing of steel products

3. Main Technical Parameters:

4. Main Unit Feature:
4.1 Rigid floor-standing frame loading structure with upper space for tensile and lower one for compression and bending test
4.2 Precise ball screws withstand the whole loading with long-life use and compact layout.
4.3 Speed control system is set under the table and comprises the synchronous toothed belt and pulley for high-efficient transmission, which are featured with low noise and maintenance free.
4.4 Fixed crossbeam as upper ones, and sits above the frame and with middle crossbeam as loading beam with smooth travel when testing . The high-accuracy sensor is installed below the crossbeam.
4.5 Load automatic withstanding,, stress, strain control, cycle control and self programming.
4.6 High precision load sensor for guarantee accurate and stable measure
4.7 Wide crossbeam travel speed from 0.05 ~ 500mm / min
4.8 Overload protection: as test force exceeds 2%-5% of the maximum test force of each file, overload protection, it will stop. 

5. many optional test fixtures, offer customize fixtures too

6. Data Acquisition system
61. The data acquisition system of machine consists of two high precision A/D conversion channel and the maximum resolution should be 1/300000 (minimum)
6.2. USB powered data -logger with USB 2.0 and RS- 232 pc interface, 5-keys joystick, 2MB RAM, Automatic recognition facility, Internal signal generator and 12-bit conversion resolution

7. Software

many test method and allow add new test method by client

different test curves can be put together for comparing

different control mode, displacement control, load control, self-edited test steps control
