1.0 Overview & Operating Principle

8.0 DX2 Special-Purpose Models

DX2 and 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, bers, wires, optical bers, tapes, etc. They employ the 3-roller
principle for tension measurement where the outer two reference guide rollers
remain xed 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.

NOTE: While illustrations show the Type DX2 Tension Meter, all references
apply to the Special Purpose Tension Meters as well.

NOTE: DX2 Special Purpose Types, including FX2, TX2, DX2F, RX2/BX2 and
KXB, are shown in the Appendix at the end of these instructions. They
all use the3-roller principle for tension measurement except that head
congurations and roller assemblies are different, having been designed
for special applications, as noted in the Appendix.

Essentially, all DX2 Special Purpose
models operate in a manner similar
to the standard Type DX2. In addition,
however, they offer special rollers an
head congurations for specic
applications.
