Torque and Bending
Weighing and Force Measurement Practice
The basis for all electronic force measurement or weighing is measurement
of stress in a loadcell body. To obtain optimal results it is necessary to
establish a few basic rules, otherwise the effect may be a nonlinear or non-
repeatable response. Read and follow these tips and see the illustrations on
the next page.
For accurate performance the force acting on the unit must be in line with
the unit.
Insure shackles are oriented parallel with the instrument. Apply load in the
center of the shackle bow.
A proper fitting pin is important in order to generate an even stress distribu-
tion and avoid yield stresses. To achieve published accuracy you must use
the shackle pins provided by Dillon.
Torque and bending should be avoided. Use swivels on the lifting wire for
anti-torque and avoid side forces.
Certified shackles and lifting gear should always be used in accordance to
local laws and federal legislation. Insure all hardware, fittings and line used
to sustain the load are properly sized and rated for the installation. Have the
system evaluated by a qualified engineer if any question or uncertainty
exists.
