Tension meter with large, easy to read scale

Special Features

The analog display of tension meter DN1 shows changing and fluctuating tensions fast and enables an optimal process adjustment

The built-in material thickness compensator compensates different material diameters for a particular range (only DN1-1000 and higher ranges).

Large, easy to read scale (54 mm Ø)

Linearized scale provides a better reading

Tension meter with shock-resistant movement

Filament guide and roller shifting mechanism ensure easy acquisition of the running material

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

Special calibration is available

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

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.

Specifications subject to change without notice!


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 DN1

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

  1. Air Damping Code A

    Tension meter DN1 and dashpotFor tension ranges 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 spooling and winding machines. This assures steady tension readings on scale.

  2. Special Lever Code L

    Tension meter DN1 with special leverStandard for tension meter DN1-20K-L and higher ranges.
    Facilitates acquisition of the running material when measuring high tensions. Reduces force necessary to extend outer rollers: Recommended for tension meter DN1-10K.
