To calculatethe force rating, first select theappropriate wrap configuration,1, 2 or 3. Then calculate theforce using the formula for thatwrap configuration.Selection of Force RatingWRAP 1Tension Force,F T above horizontalThese formulas allow for atension transient of 2 times theaverage tension. Thus, in somecases, it may be appropriate touse a sensor pair with a forcerating slightly less than thecalculated net force.In some applications, a transducerroll can be so heavy thatits weight takes up the operatingrange weight of the sensors. IfWRAP 2Tension Force,F T below horizontalthis happens, it may not bepossible to zero the tensionwhen the transducer roll isunloaded. This is caused byexceeding the adjustmentrange of the tension controlleror meter.To determine if your idler roll istoo heavy, compare the forcerating with the effective weightof the roll using this formula: IfW COS (A) is more than 95%WRAP 3Tension Force,F T is horizontalof the force rating selected, thetension meter or controller cannotbe adjusted to zero. If this is thecase, one or more of thesechanges must be made toreduce W COS (A) to less than95% of the force rating:• Reduce the sensor roll weight• Increase angle (A)• Use the next higher forcerating (this is not desirable assensor signal output is reduced)303
