Electronic tension meter manufactured for applications with yarns, fibers, wires, cables, optic fibers, tire cord, webs & warps, tapes & bands, tows, ribbons etc.
Easy mounting For online application, built-in material thickness compensator with material sample inserted
Field adjustment function
for fine tuning of the calibration for materials which differ from factory standard calibration material; the displayed value can be increased or decreased in ±1.5% increments.
The DTMB provides critical process information required to meet today's strict quality reporting systems mandated under ISO 9000 guidelines.
Optic Fibers | Limited Access |
• FTMB Uses low-inertia 32 mm dia. rollers for fragile materials sensitive to bending over a small radius. Rollers are available in plastic or aluminum. Tension Ranges (g): 0-200, 0-500, 50-1000, 200-2000 |
• DTFB Long, flat fingers and miniature V-grooved rollers permit measurement in areas with limited space or tightly grouped filaments. Tension Ranges (g): |
|
|
Tapes and Bands | Lever Model |
• RTMB • BTMB
Cylindrical rollers are available in 10, 15, 20 and 30 mm widths with single or dual flanges. |
• DTMBL The Lever is used instead of the thumb-piece for high tension applications. The lever is optional on the 10 Kg and 20 Kg models; it is standard |
