DN1
Tension Meter

12 Tension ranges available
from 20 – 120 cN up to 5 – 50 daN

Application textile industry: up to 50000 tex
Application wire industry: up to Ø 2.5 mm Cu

Rugged mechanical tension meter for versatile use in textile, fibre and wire industry

Hand-held instrument for tension ranges up to max. 50 daN

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 up to DN1-20K-L).
  • 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

Material Thickness Compensator

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

** Suitable for 95 % of applications – PA = Polyamide Monofilament
*** deviating measuring head width with Code V1

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 DN1

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

ATTACHMENT

Code A – Air Damping

For 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.

 

 

 

 

 

 

 

 

 

Special Lever Code L

Standard 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.

DELIVERY INCLUDES

Tension meter DN1 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
