3. GTSCM/GTSDM load cells are designed to be mounted under standard, self-aligning pillow block bearings, which
support an idler roll shaft. Two GTSCM/GTSDM load cells should be used to measure tension on one idler roll.
Mount the load cells on opposite sides of the machine, on a clean and flat surface of the machine frame. The load
cells can be mounted in any orientation. The maximum and minimum bolt penetration for the bottom mounting
threads are given in table 1. DO NOT EXCEED THE SPECIFIED MAXIMUM BOLT PENETRATION.
CAUTION –Possible damage to load cell.
Do not exceed the specified maximum bolt penetration.
4. OBSERVE THE WRAP ANGLE OF THE WEB AND INSURE THAT THE RESULTANT FORCE DUE TO WEB
TENSION IS IN THE “YES” ZONE AS INDICATED ON THE LABEL. If not, turn the load cell around and recheck the
direction of the resultant force.
NOTE: If the resultant force is “upward” (away from the load cell), reverse the black (-s) and white (+s) signal leads at
the readout or control terminal block.
5. When installing the pillow block bearing, DO NOT EXCEED THE SPECIFIED MAXIMUM BOLT PENETRATION. The
maximum and minimum bolt penetration for the top mounting threads are given in table 1.
CAUTION –Possible damage to load cell.
Do not exceed the specified maximum bolt penetration.
6. If the shaft is exposed to higher temperatures during operation, an expansion type pillow block bearing must be used
to accommodate shaft expansion.
7. The sensing roll must be concentric and balanced for high speed operation.
8. Connect the load cell to the MAGPOWR readout or control with shielded cable.

The top plate adapters are installed on the top of the load cell and secured with the 4 screws installed in the 4
counterbored holes in the plate. Tighten the bolts to 132 Nm [97 Lb-Ft] for the GTSCM and 682 Nm [503 Lb-Ft] for the
GTSDM.
The bottom plate adapters are installed on the bottom of the load cell and secured with the 6 screws installed in the 6
counterbored holes in the plate. Tighten the bolts to 132 Nm [97 Lb-Ft] for the GTSCM.
CAUTION –Possible damage to load cell.
The Adapter Kit must be installed on the load cell after the pillow block mounting holes or the base
mounting holes have been drilled and tapped. Do Not drill and tap holes with the Adapter Kits installed on
the load cell.

SELECTION AND SIZING
To properly size any model GTS load cell select the case (which resembles your application) from the examples shown
below. Using your known maximum tension, roll weight, and angles as shown, apply the equation to calculate a “load
rating” L. Select a load cell with a load rating greater than that calculated.
Example: In case 2 below,
T = 1500 lbs., X = 180º, Y = 30º, w = 500 lbs.
then L = ( 2*T * sin(X/2)*(cos Y + sin Y) )+w/2
L = ( 2(1500) *sin 90º *(cos 30º + sin30º) )+ (500/2)
L = ( (3000)(1)(0.866 + 0.500) )+250
L = 4348 lbs.
Select a pair of GTSC2500M load cells
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
L = 2 * T * SIN(X/2) * (COS(Y) + SIN(Y) ) +/- (W/2)
See Cases Below
Resultant force direction must be in quadrants 1 or 2

NOTES:
Angle Y cannot exceed 45º
The second term (roll weight “W"/2) of the equation must not
exceed 50% of the selected load cell rating. If it does exceed
50%, select the next larger load cell rating.
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.
