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.
