I-E DESCRIPTION OF OPERATION

The total resultant load per cell (JT) is calculated by

resolving web force vectors acting upon the

Tensioncells, with respect to the Loading Line (OX). (JT)

is the resultant of both TENSION and TARE loads, PER

CELL! (See Figure 6)

The intrinsic design of Comptrol Tensioncells allows the

location of the Resultant Load of Web Tension (H) on

any angle with respect to the Load Line (OX). Note,

however, that the Total Force vector (JT) must always

be calculated on the line (OX).

Any force vector falling on the line (OR) (through the

pivot point of the C-Flexure) will produce no deflection,

and thus no change in electrical output.

Rotating the Tensioncell on its mounting bolt changes

the force vectors on the cell. This feature makes it

possible to minimize the tare component and maximize

the load signal output.

The resultant tare is minimized by mounting the

Tensioncell so that (N) is 149° (See Figure 7A and 7B)

or so that (N) is 329° (See Figure 8A and 8B).
