Tension Meters DTBB, DTBX

9 Tension ranges from 2 - 200 cN to 5 - 50 daN

Special tension meter for measuring all kinds of tapes, such as textile ribbons, films, foils, fibre bunches etc.
Cylindrical rollers pointing toward the operator (width max. 30 mm)

The tension meter is equiped with both-sided flanged outside guide rollers for better filament guide

Special Features

  • Dual-flanged outer guide rollers with various widths, from 7 mm to 30 mm
    (single-flanged rollers optional, recommendable if the material beeing measured is wider than the tape roller)
  • Standard calibration of model DTBX only for one material
  • Calibration to customer supplied material is available
  • 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
  • Roller shifting mechanism ensure easy acquisition of the running material
  • Ball-bearing mounted, tape 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
When selecting the instrument for your specific application, please keep in mind that:
1. Rollers of different widths are not interchangeable by the user.
2. The roller width should correspond with the width of the material to be measured. 
    Otherwise incorrect measuring results may occur and the instrument may be damaged.

SCHMIDT has the solution to any tension measuring problem! Please contact us to discuss your application requirements.
To assist you in selecting the right tension meter for your specific application, please furnish:
- Kind and dimensions of the material to be measured
- Expected tension range
- Material sample of about 5 m

Other tension ranges and measuring head widths available on request.
Other units of measure available - g or kg.
* SCHMIDT calibration material textile ribbon or film, depending on tension range and roller width
** Outer distance between outside guide rollers

Important for your order: Please specify model and roller width!
Small dual-flanged outer guide rollers are standard. All 3 rollers can be equipped with one flange, if the material to be measured is wider than the rollers. Please request when you order.

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.
