1.0 OVERVIEW & OPERATING PRINCIPLE
ZD2 and ZF2 Tension Meters are hand-held, mechanical instruments which accurately
measure the running as well as static tensions of a wide variety of process materials
including yarns, fibers, wires and optical fibers. They employ the 3-roller principle for
tension measurement where the outer two reference guide rollers remain fixed during
measurement to establish a wrap angle over the middle sensing roller. The middle
roller, acting against an internal calibrating spring, is displaced relative to the
running line tension. This displacement is converted to a rotary motion to turn
a pointer on a scale to give a reading in grams tension.
