Special finger support located on the rear side reduces the effort to move the outer roller assembly

Custom-built configurations and special calibration are available

Standard Features

Everything in operator’s view:
– the guide rollers
– the measured material
– the readings

Ball-bearing mounted, V-grooved guide rollers

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


Material thickness compensator

For better accuracy the material to be measured or a similar material with the same diameter should be inserted.


Finger support for DX series

Finger Support

We recommend mounting a finger support for higher tension ranges of tension meter DX2

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.

SCHMIDT has the solution to any tension measuring problem! Please contact us to discuss your application requirements. Special designs are available.
To assist you in selecting the right tension meter for your specific application, please furnish:

  • description of your application
  • kind and dimensions of the material to be measured
  • expected tension range
  • line speed of the material to be measured
  • material sample of about 5 m

  1. Code A - Air Damping

    Tension meter DX2 and DashpotFor tension range from 20 – 120 cN up to max. 400 – 5000 cN.
    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 scale.

  2. Code L - Special Lever

    Zugspannungsmesser der Modellreihe DX mit einem AufsatzdrückerStandard for tension meter DX2-20K-L.
    Facilitates acquisition of the running material when measuring high tensions. Reduces force necessary to extend outer rollers. Recommended for tension meter DX2-10K.

  3. Code M - Memory Pointer

    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.

At Sewing Machines
Drawing of tension meter DX2 with a sewing machineBesides strength and the kind of stich the tension of the upper and lower thread is important for the solidity and the image of the seam. Tension determines the stitching length. For measuring the upper and under thread of non-operating machines DX2 series is recommended. The tension meter is used after the yarn break and the thread unwinded by hand. The most used models are DX2-400, DX2-1000 and DX2-2000. These tension meters are often equipped with a memory pointer code M, to read the measuring value after finishing the measurement. Further tension meters for measuring the thread tension at sewing machines are the models ZF2 and Q, as well as series DT, ET and TS.


Seam with correct and incorrect adjusted thread tension

Left: Seam with correct adjusted thread tension
Right: Too much yarn results in insufficient linkage of the seam with the used material
