DN1 Durable tension meter for high tensions


Made in GermanyDurable tension meters for a wide range of applica-tions in the textile, fiber and wire industries.

The DN1 analog tension meter shows changing and fluctuating tensions fast, itenables an optimal process adjustment .The built-in material thickness compensator compensates different material diameters for a particular range (only DN1-1000 and higher ranges). The scale (54 mm Ø) is easy to read, the linearized scale provides a clear reading. The filament guide and roller shifting mechanism ensure easy acquisition of the running material.


Features
  • Large, easy to read scale (54 mm Ø)
  • Shock-resistant movement
  • Filament guide and roller shifting mechanism ensure easy acquisition of the running material
  • Ball-bearing mounted, V-grooved guide rollers
  • Special calibration is available
  • Specific Test Report with calibration test report optionally available
  • Linearized scale provides a better reading
  • Built-in material thickness compensator improves accuracy for changing diameters on DN1-1000 and higher ranges
  • Everything in operator's view:
    - the guide rollers
    - the measured material
    - the readings
  • Each instrument is individually calibrated for highest accuracy
  • Rugged aluminium housing

Other units of measure available - g or kg.
* Depending on model, either width of filament guide or outer distance between outside guide rollers
** Suitable for 95% of applications - PA = Polyamide Monofilament
***MTC = Material Thickness Compensator

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

Options
Code A: Air DampingCode L: Special Lever

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.

Facilitates acquisition of the running material when measuring high tensions.
Reduces force necessary to extend outer rollers: Recommended for tension ranges of 10 daN and higher.
