GTS Sizing FOR SIZES A AND B, REFER TO STRIPED QUADRANTS FOR SIZES C AND D, REFER TO SOLID QUADRANTS Load Cells & Readouts CASE 1: CASE 2: CASE 3: CASE 4: + For resultant in quadrant 1 - For resultant in quadrant 2 (shown) - For resultant in quadrant 1 + For resultant in quadrant 2 (shown) + For resultant in quadrant 1 - For resultant in quadrant 2 (shown) - For resultant in quadrant 1 + For resultant in quadrant 2 (shown) Step 1 Select the mounting orientation which resembles your application from the examples shown above. Step 2 Using your known maximum tension, roll weight and angles as shown below, apply the following equation to calculate a "load rating" L. L = 2 T SIN(X/2) (COS Y + SIN Y) +- (W/2) SEE CASES ABOVE (RESULTANT FORCE DIRECTION MUST BE IN QUADRANTS 1 OR 2) FOR SIZES A AND B L = SENSOR LOAD RATING T = MAXIMUM TENSION R = RESULTANT FORCE DUE TO TENSION W = ROLL WEIGHT X = WRAP ANGLE Y = ANGLE BETWEEN RESULTANT FORCE DIRECTION AND THE CENTERLINE OF THE LOAD CELL FOR SIZES C AND D NOTES: Angle Y cannot exceed 45˚. The second term (roll weight "W") of the equation must not exceed 50% of the selected load cell rating of both sensors combined. If it does exceed 50%, select the next larger load rating unit. When the resultant force (R) is pulling in a direction away from the load cell, the signal leads must be reversed at the terminal block of the control. Load Cells & Readouts 69
