Tension Meter DTMB

9 Tension ranges from 0.1 - 200 cN to 5 - 50 daN

Electronic tension meter for applications in textile and wire industry. Versatile usable.
Applications in textile industry: e. g. 50 up to max. 50000 tex
Applications in wire industry: e. g. 0.08 up to 2.2 mm copper wire

Basic unit for easy operation

Special Features

  • Microprocessor controlled tension meter for highest accuracy
  • Measuring principle: double beam in bending with strain gauge
  • Selectable update rates (0.5, 1, 2 or 4 seconds) to provide
    steady readings when tensions fluctuate (electronic damping)
  • Measuring frequency: 62 measurements/second
  • The display ot the tension meter shows averaged values calculated during the update
    interval t1 e. g. every second 1 x

  • Saving MIN, MAX and PEAK values during a user-selected period. These values can be recalled at the display.
  • Zero adjustment feature permits use of the tension meter in various measuring positions, maintaining highest accuracy
  • Calibration to customer supplied material is available (up to two different material calibrations)
  • Tension meter with built-in material thickness compensator improves accuracy for changing diameters (from tension range - 500 cN)
  • Hand-held unit with built-in mounting holes permit fixed installation for online use
mounting and material thickness compensator tension meter model DTMB Easy mounting: For online application

Material thickness compensator: For better accuracy the
material to be measured or a similar material with the same
diameter should be inserted

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
  • Ball-bearing mounted, V-grooved guide rollers
  • Tension meter with rugged aluminium housing
  • Battery operated (AC adapter for continuous operation available)
  • 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
