How to choose the tension meter of the film roll to measure the tension of the film roll?

In the production process of wide-format film materials, a film roll is required to wind the film. The tension of the film during winding needs to be measured with a film roll tension meter. How to choose a suitable roll What about the tension meter of the film machine? This should be considered in terms of the width and range of the membrane material. If the width of the film is less than 50mm and the tension is less than 50KG, you can choose the NTW series film roll tension meter produced by Shenyang Baitan Technology Co., Ltd. for tension measurement. The specific model is also determined according to the specific width and tension of the membrane material. If the width of the film is greater than 50mm, the hand-held tension meter for the film roll cannot measure the tension of the entire cross section of the film. It can only measure the tension of part of the film from both sides, and then calculate the tension of the entire film tension.

Below is the detailed information of the NTW series.

NTW Series Special purpose models for foil and metal foil tension measurement, suitable for foil within 50mm width. 

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.
