Product Description

Ccomputer-controlled electronic tensile testing machine is mainly used for testing mechanical properties of various metals, non-metals and composite materials such as tensile, compression, bending, shear, stripping, tearing, etc. The system adopts microcomputer closed-loop control, which can realize constant velocity displacement, constant velocity stress, constant velocity strain and can be programmed. The design of the test machine has the characteristics of beautiful appearance, convenient operation, stable and reliable performance, no pollution, low noise, and high efficiency. The design of the auxiliary equipment is matched with the main machine. The structure is wedge-type translational and manual rotary clamping. The specimen is not subject to additional force. Convenient, reliable and non – slip clamping.

The working environment should be free from vibration and dust. At room temperature (15-25); Humidity < 70%; Surrounding no vibration, no corrosive medium, no strong magnetic field interference; Power supply voltage fluctuation not exceeding 10% of rated voltage.

Features
The machine adopts the all-digital servo speed regulation system with high speed regulation and stable performance and servo motor as the drive system, the all-digital controller as the core of the control system, and the control and data processing software with Windows as the operation interface to realize the test force, test The screen display of force peak value, beam displacement, test deformation and test curve, all test operations can be automatically completed on the computer through the mouse. The good humanized design makes the test operation easier. Combining the above technologies, the machine can achieve almost perfect closed-loop control of parameters such as test force and displacement, and can realize control modes such as constant stress and constant displacement, and can switch between various control modes smoothly. The machine fully meets the requirements of the national standard GB/T228-2002 “”Room temperature tensile test method for metal materials”", and can perform tests and data processing according to GB, ISO, JIS, ASTM, DIN and various standards provided by users, and has good of scalability.
