Applications:

Model SXW Series Computer Control Electronic Relaxation Testing Machine is designed for the relaxation tests of steel wires, indented wire, and galvanized steel wire etc. This machine adopts vertical load frame with great rigidity, AC servomotor with zero clearance & great torque precise reducer to drive the screw to carry out the adjustment of the test space. the tension of specimen and keeping of the load force. to complete the relaxation test. the machine is equipped with especially designed industry PC. The control and data processing system of IPC has very high reliability, which can meet the requirements of data processing, displaying, storage and data analyzing demanded by the relaxation test that over 1000 hours.

Control system Features:

1. The special English version software can draw test curve in real time, such as stress-time, temperature-time, relaxation rate-time curves, etc.

2. Automatic calculate 1000 hours stress relaxation rate of the specimen, etc

3. High precision temperature sensor will record the influence of room temperature variations in load curve.

4. Servo close-loop control can guarantee the control accuracy for load, displacement and deformation.

5. Constant load and constant displacement control can be selected.

6. Automatically calculate stress relaxation properties of the specimen and print complete test diagram and test report.

7. Over-load, over-displacement protection, and other safety methods are applied.

8. Capable of re-analyzing test results, and partial zooming of testing curves at will. System support saving, instant retrieving and inspection of test results.

9. After test, the test data can be shown when the mouse icon points

10. Optional calibration system can be offered

11. Test reports can be as Excel form, etc.

12. Meet ASTM, ISO, BS standards for strand.
