Economical low tension measuring instrument for checking fibers, yarns and fine wires in areas with limited access. 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.
|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.
This model is recommended for all other applications where miniaturized rollers are not necessary.
