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.

Miniaturized rollers make these models ideal
for delicate fibers, low tensions or when
access space is limited.

Recommended for all applications where
miniaturized rollers are not needed.
