One purpose
WDW series microcomputer control electronic universal testing machine (series of geotextile * gantry structure), mainly for all kinds of glass fiber geotextile, plastic warp knitting geotextile, the geotextile synthetic material, geotechnical grille tensile, bursting, punctures and other mechanical properties test. Precision automatic control and data acquisition system, the data acquisition and control process of the full digital adjustment. In the test, the maximum load carrying capacity, pressure, tensile strength, compressive strength, elongation deformation, elongation and other technical indexes are detected. After the test is over, the test parameters are automatically calculated by the computer according to the test parameters, and the corresponding test results are displayed, and the test parameters can be displayed after the end of the experiment, and can also be connected to the printer for printing output.
Two, features
1 with remote control box, can realize the fast / slow adjustment of the beam, the operation is flexible and can be switched freely.
2 function, intelligent, efficient, and quick to return to the initial position after the test is finished.
3 have any working position limit protection function and overload, over current protection function, reliable, safe.
4 self built a powerful test database, test data can be saved, query, call
5 can achieve constant rate force control, constant rate stress control, constant rate deformation control, constant speed control, constant speed control, constant speed control, constant speed control, constant speed control, constant displacement control and user programming control.
6 can be switched to display a variety of test curves: stress-strain curve, force deformation curve, force displacement curve, force time curve, deformation time curve, displacement time curve, force strain curve. Local amplification of experimental curves and comparison of multiple curves.
7 increase the attachment can also complete other materials of the tensile, compression, bending, torsion and other test test
