Tension Meter DXF

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

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

  1. Air Damping Code A

    Tension meter DX2 and DashpotFor 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.

  2. Schleppzeiger Code M

    Scale with pointer for reading and memory pointerFor tension range 20 – 120 cN and higher
    Retains the highest measured value (PEAK). Available for mechanical tension meters.
