DTFB - DTFX Digital Tension meter with large rollers

Made in Germany 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.

Features

Large, V-grooved guide rollers with 32 mm groove diameter, ball-bearing mounted
Special guides on the bracket assembly permit easy material acquisition
Filament guide and roller shifting mechanism ensure easy acquisition of the running material
Rugged aluminum housing
Specific Test Report with calibration report optionally available
Large bending radius assures gentle handling of the material being measured
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)

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.
