2.5.3 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:
FR = T × [cos (β + γ) - cos (α - γ)]
FRT = Tare × sin γ
FRtot = FR + FRT = T × [cos (β + γ) - cos (α - γ)] + (- Tare x sin γ)
FV
= T × [sin (α - γ) + sin (β + γ)]
FVT = - Tare × cos γ
FVtot = FV
+ FVT = T × [sin (α - γ) + sin (β + γ)] + Tare × cos γ
where:
T = Web/strip tension
FR = Force component from web/strip tension in measurement direction, R
FRT = Force component from Tare in measurement direction, R
FRtot = Total force in measurement direction, R
FV
= Force component from web/strip tension in transverse direction, V
FVT = Force component from Tare in transverse direction, V
FVtot = Total force in transverse direction, V
Tare = Force due to tare weight
α = #eflection angle on one side of the roll relative the horizontal plane
β = #eflection angle on the other side of the roll relative the horizontal plane
γ = Angle for load cell mounting surface relative the horizontal plane

General
The equipment is a precision instrument which, although intended for severe operating conditions,
must be handled with care. The load cells should not be unpacked until it is time for installation.
To achieve the specified accuracy, the best possible reliability and long-term stability, the load cells
must be installed in accordance with the instructions below. See also 6.4 Fault Tracing in the
Mechanical Installation.
• When a load cell type PFTL 101AER or PFTL 101BER is used for an acid resistant
application it is recommended to use adapter plates and screws of austenitic, acid resistant
steel.
Information
For all types of installations of these load cell types, austenitic steel must be used,
preferably acid resistant or stainless steel.
