Microcomputer-controlled Electronic Creep and Stress Rupture Testing Machine

Model: WDR-5000W

Application: The rubber creep testing machine is primarily used for tensile and compression creep rupture tests on non-metallic materials under ambient conditions, as well as low-cycle creep fatigue tests and creep-fatigue tests. The WDR5000 series microcomputer-controlled electronic creep and stress rupture testing machine is a new series of testing equipment developed by our company, based on years of experience in manufacturing electronic universal testing machines and creep rupture testing machines.

Product Features:

1. Real-time dynamic calibration function of the testing machine controller: Ensures long-term measurement accuracy of test force, displacement, and deformation.

2. Computer software with automatic alarm and error handling: Redundant backup system with control computer and data processing computer; backup computer automatically takes over if main control computer fails.

3. Ensures long-term measurement stability; test force and deformation measurement deviation shall not exceed ±0.5% over 1000 hours.

4. High resolution in force and deformation measurement (24-bit), with full-range unchanged resolution.

5. Sensor channel bandwidth up to 5 Hz, ensuring authentic and effective test data and curves.

6. Force sensors are US-made, offering high accuracy and long-term stability.

7. Large deformation extensometer is bidirectional, using high-precision grating ruler with high measurement accuracy, strong heat resistance, and anti-interference capability.

8. Testing machine controller features automatic zero adjustment and automatic calibration.

9. Multiple protection functions including overload, over-travel, over-voltage, over-current, and over-temperature.

10. Equipped with timing device; timing starts and displays when load reaches set value during test.

11. Position limit switches or alarm controls and interlock protection between various actuators.

12. Optional UPS ensures automatic maintenance of test state and alarm during sudden power outage, preventing test failure and loss.

13. Integrated control cabinet houses multiple controllers; one computer can monitor 5 or more testing machines simultaneously, with each controller operating independently without interference. (Customers can choose testing machine hosts of different capacities as needed for broader application and convenience.)

14. Equipped with SMS modem function for unattended long-term tests, periodically sending test status and corresponding data results to the operator. (Key feature)

15. The testing machine is a fully electronic creep testing machine capable of conventional creep and stress rupture tests, as well as stress relaxation tests, high-temperature short-term tensile tests, periodic loading tests (load spectrum tests), and low-cycle fatigue tests.
