Principle
The testing machine uses a precision digital motor and a digital speed control system as the driving device. After deceleration by the deceleration system, the precision screw pair is driven to load to achieve smooth transmission and High Accuracy control. The force value data is collected through the High Accuracy Sensor, and the all-digital closed-loop control system realizes the test functions of constant stress, constant strain, and constant displacement. The single-chip microcomputer performs information sensing, data processing and action control to ensure the automation of the test process and the accuracy of the data.
Applications
Rubber, Plastic film, Woven belt, Wire and cable, Spinning & weaving products, Wire and other metals, Non-metallic, composite tensile strength and elongation testing, Research institutes, Universities & colleges, Industrial and mining enterprises, Technical supervision, Commodity inspection and arbitration departments
Steps
1. Enter the sample parameters and test parameters in advance.
2. Select the test method and set the tensile speed and sample size as required.
3. Start the test, and the screen displays the test force, peak value, speed, and operating status in real time.
4. Automatically calculate and output the maximum force value, elongation and maximum tensile strength after the test.
5. Save multiple sets of test data and results, and display and print statistical reports.
6. After the test is completed, return to the origin automatically or manually.
Notice
• Make sure that the sample parameters are entered correctly before the test.
• Choose the appropriate test method and fixture according to the test object.
• Pay attention to the upper and lower mechanical limits and electrical overload protection functions.
• To avoid overload use, the maximum load value can be set for automatic protection.
• Regularly check the transmission system and Sensor status of the equipment.
• Follow safety procedures during operation to prevent accidents.
