How to use the wire diameter compensation function of the wire tension meter correctly?

The choice of wire tension meter in the wire and cable industry is mainly based on the two parameters , one is the measured force range and the other is wire diameter range of the measured material.

For wires with a wire diameter more than 0.2mm, the wire tension meter must have a wire diameter compensation function, because the error caused by the wire diameter cannot be ignored at this time. The range of tension should be selected according to twice the process requirements. At the same time, the compensation range of the wire diameter of the wire tension meter should also be considered. Based on these two points, the appropriate wire tension meter can be determined.

When using a wire tension meter to measure the tension of a bundle of wires, it is not effective to clamp a bundle of wires into the wire diameter compensator. In this case, it is recommended to use NTW series wire tension meter from Betten Technology Co., Ltd. NTW has a cylindrical guide roller , and the wire bundle is spread on the guide roller when it passes through the guide roller. Then it is only a wire that affects the measurement angle. A wire is inserted into the diameter compensator to reflect the true diameter change.

The following is the technical data of NTW series wire tensiometer launched by Betten Technology Co., Ltd. The wire tension meter can be selected according to the measuring range and wire diameter compensation range.

The NTW series has 12 kinds of tension ranging from 1.0-200.0cN to 10.0-100.0daN. The width of the measuring head varies with different ranges.

Features:

1. The patented technology automatically resets the meter to zero , which improves the measurement accuracy and facilitates measurement.

2. Equipped with a wire diameter compensator, which compensates errors caused by different wire diameters and improves measurement accuracy

3. Equipped with lead frame and guide wheel movement structure, it is easy to capture the tested material.

4. V-groove aluminum measuring guide roller with ball bearing.

5. Rugged, non-slip aluminum case, resistant to electrical interference.

6. LIPO lithium-ion polymer battery (about 60 hours of continuous operation).

7. The tested material, the guide roller, and the screen are located on the same plane. During the test, the test data, the status of the guide roller and the tested material can be seen.

8. A maximum of 10 materials can be accurately calibrated. With the wire diameter compensator, the tested wire diameter range is larger.

9. character menu setting interface, easy to operate.

10． According to different ranges and needs, the measurement value display unit can be selected g, kg, c N, N, daN, lb

11. It can record the maximum value, minimum value, peak value and average value in the measurement process, and can also store 10 independent measurement values.

12. Programmable setting of the maximum and minimum value of the trend status bar, clearly determine the range of tension change, and have the advantages of mechanical instrument trend display.

13. Provides fine adjustment of display results. If There is a slight deviation between the material measured on site and the standard calibration material, and accurate values can be displayed without recalibration.

14. Function settings can be protected by passwords to improve setting security.

15. Betten tensiometer provides two display modes, taking into account the advantages of accurate electronic tensiometer reading and mechanical tensiometer trend display.
