D. LOAD RATING CALCULATION
The load rating of your desired tension transducers needs to
be determined prior to size selection. Load rating is calculated using
physical properties like the weight of the idler roll, the wrap angle on
the roll, your expected web tension, and the direction of force due to
web tension. The drawings below illustrate an axial (side) view of a
tension-sensing roll in a machine frame for the three general web wrap
orientations (Up, Down, Sideways). Record the information requested in
the terms B through E below. Then use the formula below the drawing
closest to your orientation to calculate your load rating, or call DFE
and we calculate it for you.
Cross out the wrap examples that do not apply.
Note: The resultant force FT points in the same direction as the arrow on the transducer.
