ZED Digital Economical tension meter for limited acces

Economical low tension measuring instrument for checking fibers, yarns and fine wires in areas with limited acces. The ZED employs a strain-gauge system to measure the running line tension on a variety of yarns, fibers and fine wires accurately.

The running material can easily be acquired by the trigger-operated roller shifting mechanism. The single-button automatic zero permits operation in any orientation and guarantees simple operation and highest accuracy.

Tension Ranges

Model	Ranges	Measuring Head Width*	Calibration Material**
ZED-200	1-200	63 mm	PA: 0.20 mm Ø
ZED-500	1-500	63 mm	PA: 0.20 mm Ø
Other units of measure are available, such as g. * Width of filament guide ** Suitable for 95% of applications - PA = Polyamide Monofilament 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.
