INTRODUCTION

The Model GTSCM/GTSDM load cell is designed to be mounted under metric pillow block bearings. All GTSCM/GTSDM

load cells are pre-drilled and tapped to accept metric pillow block bearings. Top Plate and Bottom Plate Adapter Kits are

also available to accommodate special mounting requirements. GTSCM/GTSDM load cells are compatible with all

MAGPOWR Tension Readouts and Controls.

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.

INSTALLATION OF ADAPTER KITS

WARNING –Danger of injury from crushing.

Maintenance and repair tasks on the load cell device must be performed only when the machine has been

stopped and has been secured from being turned on again.

WARNING –Danger of falling down or muscle or skeletal injury during maintenance and repair.

The load cell devices, especially the larger designs, are heavy. Appropriate equipment is to be used and

The adapter kits include the socket head cap screws required for installation on the load cell.

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.
