DXF Tension meter with large rollers for minimized material deflection


Made in GermanySpecial 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

Features
  • 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
  • Certificate of Compliance with the order 2.1 according DIN EN 10204 is included
  • Optionally available: Inspection Certificate 3.1 according DIN EN 10204 with calibration report

Tension Ranges

Other tension ranges available on request. Other units of measure available, such as g.
* Outer distance between outside guide rollers
** Suitable for 95% of applications - PA = Polyamide Monofilament

Special calibration using customer supplied samples is recommended, if process material differs significantly from the SCHMIDT calibration material in diameter, rigidity or shape. For this purpose a material sample of about 5 m should be supplied.

Options
Code A: Air DampingCode M: Memory Pointer

This adjustable mechanical air dashpot is recommended for applications in which great fluctuations of the measured tension occur, as in spooling and winding machines.
This assures steady tension readings on the scale.

Retains the highest measured value (PEAK).
Available for mechanical tension meters.
