1、 Overview of this device:

The wire elongation tester is suitable for testing the elongation characteristics of various wire and copper wire, aluminum wire, aluminum magnesium alloy wire, and iron wire metal materials. This machine adopts laser sensing technology, with high sensing accuracy and a break stop function. The test results do not require manual calculation and automatically display the percentage of elongation. This machine can also be equipped with digital display or pointer type, which can achieve synchronous display of tension and elongation during testing, improving testing efficiency. Using advanced software programming and precise electronic sensing technology to measure the tensile strength of the specimen, and automatically converting it into% values for LED display, easy to read, precise in function, and easy to operate

2、 Working principle:

The instrument consists of two parts: mechanical transmission mechanism, electrical control, and LCD display circuit. Its basic working principle is that the movable and fixed clamps of the mechanical clamping device of the instrument clamp the two ends of the sample. The synchronous motor and mechanical transmission system drive the clamp to produce displacement at a certain speed. The clamped sample gradually elongates under this tensile force until it breaks. During this process, the LCD display part of the instrument displays the percentage elongation of the sample. When the sample breaks, the motor automatically stops

4、 Product features:

1. The box body is treated with electrostatic spray paint, and the overall design is reasonable, with a tight structure and safe, stable, and accurate operation. The overall appearance of the machine is elegant;

2. The circuit adopts advanced software program design and precise electronic sensing technology to measure the tensile length of the specimen, automatically converts it to%, and automatically displays the value of the tested elongation percentage in LED;

3. The mechanical transmission system consists of a high-efficiency internal circulation screw and a constant speed motor, ensuring smooth, accurate, and noise free operation of the machine;

4. The fixture adopts advanced anti slip treatment technology to prevent the specimen from breaking at the fixture during testing and improve the success rate of the test;

5. The fixture is equipped with fixing screws. During the experiment, the specimen can be fixed on the fixture while also wrapping the two ends of the specimen around the fixing screws of the two end fixtures, which can prevent the specimen from falling into the machine after fracture and causing adverse effects on the machine;

6. The LED digital dial gauge and pointer indicate the percentage of elongation. The steel ruler displays the percentage of elongation without the need for manual calculation, and the comparison between the two results has a correction effect, making it convenient to know the accuracy of the test in a timely manner;

7. Electric wood insulation board serves as the working surface, providing insulation and making testing more convenient and accurate;

8. Optional digital display/pointer push-pull force tester to test the tensile force value of the specimen, multifunctional testing
