SXW-300 of Microcomputer Controlled Steel Strand Relaxation Testing Machine

This machine is specially used for relaxation test of steel strand, galvanized steel wire, scored steel wire and other materials. The main machine adopts horizontal structure, the working space is adjusted by lead screw, the transmission system is inside the machine base, and the whole machine has high rigidity, which ensures the accuracy of test results. The PC realizes closed-loop control of control modes such as constant velocity test force and constant velocity displacement, and program control of test process. There is no impact switching between various control modes. The computer can calculate the test results for 1000 hours from the test data within 100 hours or 200 hours, and can also carry out continuous tests for 1000 hours. The computer displays the test force and test curve in real time, stores and prints the test results, test curves and test reports, and can implement the test standards of GB/T10120-2013, GB/T5224-2014, etc.
