Digital Tension meter with large rollers to minimize bending of sensitive materials like fiber optics, carbon and technical fibers.
The model DTFB is recommended where the DTMB cannot be used.
The DTFX can be used in places where the DTMX cannot be used.
Note: This model does not include a material thickness compensator.

Other units of measure available, such as g. ** Suitable for 95% of applications - PA = Polyamide Monofilament Measuring Head Width* 140 mm (Outer distance between outside guide rollers) 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. |
