Introduction： BGD 570/571 Universal Material Tensile Machine is a new type of material machine which combines the electronic technology and mechanical transmission. It has wide accuracy acceleration and test force range，not only measuring and controlling the load and displacement in higher accuracy and sensitively，but also doing the control test by automatically of isokinetic load and displacement. It operates easily and conveniently，especially applied in inspect instruments which is used for controlling products of produce line. This series of tensile machine is mainly suit for non-metal and metal test with test load less than 20KN（BGD 570）or 50KN（BGD 571）.
The electronic universal material testing machine is mainly suitable for testing metal and non-metal materials，such as rubber，plastic，wire and cable，optical fiber cable，seat belt，safety belt，leather belt composite material，PVC，waterproof coiled material， steel pipe，copper material，section bar， spring steel，bearing steel，stainless steel （and other high hardness steels），castings，steel plates， steel belts and non-ferrous metal wires. To test their functions which include stretching，compression， bending，shearing，stripping，tearing，two-point extension（additional extension meter is required） etc.
Character：
◆ Standards：ISO 527, ISO 604, ISO 178, ISO 1209, ASTM D 638, ASTM D 903
◆ High precision sensor（use high precision ball screw as driving mechanism）
◆ Frequency of collecting data：200 times/second
◆ Can store many testing results of referenced points, calculate average value automatically, grab automatically max. value, force value at break.
◆ Set range of break point proportion：0～99% ，and can set freely according to different samples, accomplish stopped status at different position.
◆ Safety Device：Over loading, Emergency shut down, limitation device for above travel and under travel.
◆ Collect date synchronously, conversable full 24 bits AD codes,, resolution arrives 1/500,000, surpass all competitors.
◆ More than one thousand clamps and grippers for selection.
◆ Support multi-sensors, can equip with a few sensors at the same time for different range.
◆ User can calculate elastic modulus，yield point，constant residual strength，constant elongation， constant force deformation and maximum strength. There are other special professional calculations， such as the calculation of belt stripping and the elongation at yield point.
◆ Optional measure and control system of professional test machine，which can realize the closed loop of force value，deformation and position，so that the tensile machine can carry out curve control tests freely，such as low frequency cycle（fatigue）test，step test and force value holding（creep）test.

Measure and Control System Introduction
We use newest system which was developed in 2008. With strong functions and convenient application such as language conversion, translate automatically testing results, units conversion, manage sample shape, manage users, process data, generate report etc., This system uses newest tools --Visual Studio .Net 2005 which is developed by Microsoft . With strong function and friendly windows, it become a developing tool for new generation operation system, and arrive more than 90% areas and population of global.
The Characteristics of Software:
◆Operating interface attached with graph，image：intuitive and convenient to use，and it will decrease the operation error by voice mentioned，improving the reliability at the same time.
◆MS-ACCESS database technology and SQL technology：it is not only applied for data preservation and processing standardization，but also convenient for connecting to Intranet or Internet. It can also connect Word or Excel etc software easily. User can read original test data just through standard database.
◆Modular programming：VBScript can enlarge the user’s reporter and parameter program by automatic calculation. User can develop by secondary，it can realize stretching，compression，bending， tearing，stripping，shearing etc test functions except for software bag.
◆The curve graph function：through modular programming，real-time curve graphs will be displayed during the test，and parameter types can be selected for the coordinate axis of curve graphs. In theory， there are 169 kinds of graphs，from which parameters can be displayed.
◆Multi-sensor support：it can support 5 force value sensors，5 deformation sensors + large deformation + displacement，which expanded the test range greatly.
NOTE: The minimum requirements of PC: Windows 7/Windows 8/Windows 10 operating system, USB2.0/ USB3.0 interface, CPU 3.0 GHz, 4 GB of memory, 100 GB of hard disk, wide screen color display (the minimum resolution: 1366*768).
