C.5.2 Inclined Mounting
Sometimes it is necessary to mount the load cell on an
incline due to mechanical design constraints of the
machine or the need to have a proper force component
applied to the load cell.
Inclined mounting adds a component of tare force in the
measuring direction and modifies the force components
as shown.
NOTE
When calculating, it is important that the angles
are set into the equations with the correct signs
in relation to the horizontal plane.
