Tension Meters DTFB, DTFX

3 Tension ranges from 2 - 200 cN to 50 - 1000 cN

Special tension meter for sensitive materials as optical fibres, carbon fibres, technical fibres etc.
Hand-held unit with large guide rollers (32 mm groove diameter) to minimize material deflection

Tension meter with special guides on the bracket assembly for easy thread

Special Features

  • Large, V-grooved guide rollers with 32 mm groove diameter, ball-bearing mounted
  • Large bending radius assures gentle handling of the material being measured
  • Special guides on the bracket assembly permit easy material acquisition
  • Tension meter model DTFX is calibrated using only PA monofilament!
  • The design is otherwise according to model DTMB respectively model DTMX, but no material thickness compensator

    For additional Information, see model DTMB and DTMX

Standard Features

  • Everything in operators view:
    - the guide rollers
    - the measured material
    - the readings
  • Filament guide and roller shifting mechanism ensure easy acquisition of the running material
  • V-grooved guide rollers, ball-bearing mounted
  • Tension meter with rugged aluminium housing
