Product Details
1. Main Functions:
This machine is specifically designed for the relaxation test of materials such as steel strands, galvanized steel wires, and notched steel wires. The main unit adopts a horizontal structure, with the working space adjusted by a screw rod. The transmission system is located inside the machine base, providing high rigidity to ensure the accuracy of test results. The PC implements closed-loop control of constant speed test force and constant speed displacement, as well as program control of the testing process, allowing for seamless switching between various control modes. The computer can extrapolate test results for 1000 hours based on test data from 100 hours or 200 hours, and it can also conduct continuous tests for 1000 hours. The computer displays test force and test curves in real-time, stores and prints test results, test curves, and test reports, and can execute testing standards such as GB/T10120 and GB/T5224.
2. Main Features:
1. The sensors used in the testing machine are specially developed for relaxation tests, with minimal zero drift under long-term load, and the sensors themselves have strong resistance to relaxation and creep.
2. Closed-loop control for constant speed test force and constant speed displacement.
3. Uses a dedicated reducer for servo motors, providing high transmission accuracy and efficiency.
4. In the event of a power outage during the test, test data is not lost, and testing can continue after power is restored.
