ABB PFTL 101 User Manual

The load cell has the same sensitivity in both directions, so that the load cell can be installed in
the easiest manner.
Typical mounting arrangements are horizontal and inclined mounting.
2.5.1 Coordinate System
A coordinate system is dened for the load cell. This is used in force calculations to derive force
components in the load cell principal directions.
Where direction designations R, V and A are recognized as
sufxes for force components, F, this
represents the force component in the respective direction. The sufx R may be omitted, when
measuring direction is implied by the context.

2.5.2 Horizontal Mounting
In the majority of cases horizontal mounting is the most obvious and easiest mounting method.
When calculating the force, the equations below must be used:
F
R
= T × (cos β - cos α)
F
RT
= 0
F
Rtot
= F
R
+ F
RT
= T × (cos β - cos α)
F
V
= T × (sin α + sin β)
F
VT
= Tare
F
Vtot
= F
V
+ F
VT
= T × (sin α + sin β) + Tare
where:
T = Web/strip tension
F
R
= Force component from web/strip tension in measurement direction, R
F
RT
= Force component from Tare in measurement direction, R
F
Rtot
= Total force in measurement direction, R
F
V
= Force component from web/strip tension in transverse direction, V
F
VT
= Force component from Tare in transverse direction, V
F
Vtot
= Total force in transverse direction, V
Tare = Force due to tare weight
