Ruler tape is affected by the machine and undergoes thermal expansion and contraction, suitable for:
|
|
|
1) The thermal expansion coefficient of the contact surface between the machine and the tape is close10.5╳10-6℃-1

The main features of Doubleflex
|
|
|
DoubleFLEX has two steel strips, one of which is a measuring steel strip with a grating, and the other is a load-bearing steel strip. There is a connecting layer between the two steel strips to block the transfer of tension and isolate the influence of the machine on the measuring steel strip. In the measurement direction, the tension of the measuring steel strip can be relaxed in a clear manner relative to the fixed point. The DoubleFLEX ruler has outstanding features:1) When operating the DoubleFLEX tape without thermal induced stress, experiencing significant temperature changes, or deviating significantly from the expansion coefficient of mechanical components,It can still freely expand and contract without being affected by the thermal stress of the machine
|
|
|
；2)The DoubleFLEX tape has no mechanical induced stress during installation, and the tape disperses stress, thus maintaining high accuracy in measuring the steel strip scale
|
|
|
；3)Compared to conventional tape and simple steel tape, the installed oneDoubleFLEX tape measure
