Axis Verification Rig Under Construction.

Traditional, mutually exclusive,  single axis calibration of 3 axis
loadcells does not allow for the effect of structural changes due
to 3 axis force influences.

Our new 'prism' frame verification rig, currently under construction,
with bi-hydraulic actuators in x,y and z axis, produces 3 axis
force vectors with uncertainties one tier below our calibration
standards. The resultant force vector direction can be determined
by arrangement of the component force vector ratios.  This obviates
'angular' errors associated with mechanically arranged vectors.

The rig uses 3 off simultaneously controlled bi-directional hydraulic
rams with in line axial loadcells (our model F256) limited to ± 20 kN.
For those exotic bespoke multi axis designs we will be able to
complete 'cross talk' correction matrices. (Our user friendly F307
and F233 have simple pure outputs requiring no mathematical
manipulation).  Although one tier below our calibration standards,
classed as a verification rig, correction matrices do not require
absolute accuracy beyond our verification standard.

Planned completion is November 2002
