DXF
Tension meter with large rollers for minimized material deflection |
Special purpose model feature large rollers to minimize bending of materials like optics, carbon and technical fibers.
Fragile filaments such as fiber optics and other technical fibers may require large roller diameters and a wide roller spacing.
Note: This model does not include a material thickness compensator
|
 Large, V-grooved guide rollers with 32 mm groove diameter, ball-bearing mounted | | Filament guide and roller shifting mechanism ensure easy acquisition of the running material
| | Ball-bearing mounted, V-grooved guide rollers | | 41mm Ø scale | | Large bending radius assures gentle handling of the material being measured |
| Everything in operator's view:
- the guide rollers
- the measured material
- the readings | | Each instrument is individually calibrated for highest accuracy | | Rugged aluminium housing | | Specific Test Report with calibration report optionally available |
