DXF
Tension Meter

4 Tension ranges available
from 20 – 120 cN up to 50 – 1000 cN

Mechanical tension meter with large guide rollers (32 mm groove diameter) and large center distance to minimize bending of materials

Hand-held instrument for sensitive material as optical fibres, carbon fibres, technical fibres etc up to 1.5 mm Ø

Tension meter with special guides on the bracket assembly for easy thread

Special Features

  • The analog display of tension meter DXF shows changing and fluctuating tensions fast and enables an optimal process adjustment
  • Large bending radius assures gentle handling of the material being measured
  • Roller shifting mechanism ensure easy acquisition of the running material
  • Special guides on the bracket assembly permit easy material acquisition
  • Built-in mounting holes permit fixed installation for continuous tension measurement
  • Special finger support located on the rear side reduces the effort to move the outer roller assembly

Standard Features

  • Everything in operator’s view:
    – the guide rollers
    – the measured material
    – the readings
  • Large, V-grooved guide rollers with 32 mm groove diameter, ball-bearing mounted
  • Each instrument is individually calibrated for highest accuracy
  • 41 mm Ø scale
  • Tension meter with rugged aluminium housing
  • Certificate of Compliance with the order 2.1 according EN 10204 is included
  • Optionally available: Inspection Certificate 3.1 according EN 10204 with calibration report

Finger Support

We recommend mounting a finger support for higher tension ranges

 

Note

Tension meter DXF does not include a material thickness compensator

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

SCALES

SCHMIDT scales are manufactured according to the most stringent quality requirements. Printed scales are not used. Instead, each scale is individually marked for the instrument involved. This ensures highest quality. Our special procedure makes it possible to provide tension meter DXF

  • calibrated to custom supplied material
  • fine tuned to a specific tension range
  • other units of measure such as g

ATTACHMENT

Code A – Air Damping

For tension range 20 – 120 cN and higher
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.

 

 

 

 

 

 

 

 

Code M – Schleppzeiger

For tension range 20 – 120 cN and higher
Retains the highest measured value (PEAK). Available for mechanical tension meters.

DELIVERY INCLUDES

Tension meter DXF with carrying case, operating instruction in German or English, (as requested), Certificate of Compliance with the order 2.1 according EN 10204 free of charge
