Inclined Mounting

Inclined mounting means arrangements in which the load cell is inclined relative to the horizontal
plane. In some cases this is the only option.
When calculating the force, the equations below must be used:
F = T × [cos (β + γ) - cos (α - γ)]
R
F = Tare × sin γ
RT
F = F + F = T × [cos (β + γ) - cos (α - γ)] + (- Tare x sin γ)
Rtot R RT
F = T × [sin (α - γ) + sin (β + γ)]
V
F = - Tare × cos γ
VT
F = F + F = T × [sin (α - γ) + sin (β + γ)] + Tare × cos γ
Vtot V VT
where:
T = Web/strip tension
F = Force component from web/strip tension in measurement direction, R
R
F = Force component from Tare in measurement direction, R
RT
F = Total force in measurement direction, R
Rtot
F = Force component from web/strip tension in transverse direction, V
V
F = Force component from Tare in transverse direction, V
VT
F = Total force in transverse direction, V
Vtot
Tare = Force due to tare weight
α = Deflection angle on one side of the roll relative the horizontal plane
β = Deflection angle on the other side of the roll relative the horizontal plane
γ = Angle for load cell mounting surface relative the horizontal plane
