DTVB - DTVX Digital tension meter with measuring head rotated by 90°


Made in GermanyTension meter with small rotated measuring head, where access space is limited or where filaments run close together.
The model DTVB is recommended where the standard model DTMB cannot be used. The model DTVX is a special purpose model for when the standard model DTMX cannot be used.

Note: This model does not include a material thickness compensator

Features
  • Turned-up outer finger edges guide the running filament into the roller grooves
  • Small, ball-bearing mounted, V-grooved guide rollers
  • Filament guide and roller shifting mechanism ensure easy acquisition of the running material
  • Rugged aluminium housing
  • Certificate of Compliance with the order 2.1 according DIN EN 10204 is included
  • Length of measuring head approx. 59 mm
  • Everything in operator's view:
    - the guide rollers
    - the measured material
    - the readings
  • Ball-bearing mounted, V-grooved guide rollers
  • Battery operated (AC adapter for continuous operation available)
  • Optionally available: Inspection Certificate 3.1 according DIN EN 10204 with calibration report
