It depends on how the wrap angle varies. Divide the wrap into two angles, entry and exit. If both angles vary then more equipment needs to be installed (such as a running line tensiometer) to get an accurate line tension reading. If only one angle is varying then a dual axis load pin is applicable. Pin alignment is critical but the LCI Series display can accommodate for errors generated by misaligned dual axis load pins. Refer to the operating manuals for more detail. Dual axis load pins are tricky to install and calibrate. If one of the angles varies only slightly, then another possible approach is to use a single axis load pin and calibrate at an intermediate wrap angle (middle of the wrap angle variation). The operators must then assume the tension system will have errors at the angle variation extremes.
