Types of tensile testing machines>
< p class=MsoNormal style=text-indent:2em;>As an important testing instrument, the tensile testing machine is widely used in various industries, resulting in many different types, but are derived according to the car market items and industries, provided they are divided into the following four categories:p>
1-pointer tractor
This is an old-fashioned low-precision tractor, and it's currently being essentially eliminated, but in some places that require relatively low-precision manufacturers, or continue to use.
2 Digital Display Tensile Testing Machine
This type of testing machine can be considered as the second generation tensile testing machine that Mainly used to measure tensile, tearing and maximum elongation of materials. Mechanical properties such as length can also be used to measure the compressive strength value of the material. It belongs to the semi-automatic mode of operation. It will stop automatically if it breaks and it can be set to return automatically. The handling is very easy. , Intuitive and clear, relatively high measurement accuracy, can save data automatically, often used in factory quality control.
3 Universal computerized testing machine
Currently, the universal computer style is furthest fromWidespread testing machine and testing software interface can realize constant speed, fixed displacement and other control modes, multi-level control, which can meet different testing needs. Overload emergency shutdown, automatic breakpoint shutdown. It works with seven gears, can shift automatically and covers a large number of current international mainstream test standards. Multiple languages can be switched at will, the test results can be output in EXCEL/TEXT/HTML and other formats, the data can be automatically archived, auto-totalized, and other values can be determined.
4-servo universal testing machine
There is basically no difference between the servo universal testing machine and the computer universal testing machine except for the main instruments wie Servo traction machine motor and sensor The components are imported, therefore the overall instrument is more stable than the computer traction machine, with higher measurement accuracy, more convenient operation steps, and a higher degree of automation. The test results can be printed out in batches and special function modules can be freely added.
