Determining the Tension Range

Determining the Tension Range
The tension range can be calculated for every wrapping angle with this formula:

FN = Nominal load (Multiplier * FZ)
FZ = Line Tension
α = Wrapping angle at the guide roll

FN = 2 * FZ * sin( α/2 )

When selecting the nominal measurement force it is necessary to take into account the weight of the guide roll and raise the nominal load respectively, particularly when working with small nominal forces.
