Steel Strand U And V Notch Tester Wdw-500s

WDW-300S Steel Strand Stress Relaxation Testing Machine
(new structure, easy calibration, 300kN) 

WDW-500S Steel Strand Stress Relaxation Testing Machine
(new structure, easy calibration, 500kN) 
 

This machine is used to do stress-relaxation test of steel strand, galvanized steel wire, indented wire etc metal materials. The host machine adopts horizontal structure, adjust work space by lead screw, and the transmission system is inside the machine base, the machine has very high stiffness, which guarantee the accuracy of test results.
PC realizes variety of control modes, which include constant test force, constant displacement etc closed-loop control and test process control, all kinds of control modes can be switched without impact.
The computer can calculate the test results of 1000 hours according to the test data not more than 200 hours, it can also do continuous test of 1000 hours. The computer real time displays test force and test curves, can save and print the test results, test curves and test report.
New feature: the load frame is equipped with load frame, which is convenient for future load calibration.
New need to buy any additional load frame for calibration.
