Tension Modules
Originally "S" cells
were made to replace levers and dials in mechanical scales.
Applications
like this did not require matched cells as there is only one
cell to calibrate.
Some "S" cells
vary as much as 5-10% for the same capacity rating.
.
When multiple
"S" cells are used for suspending hoppers the matching
by manufacturer will affect the expected accuracy. Manufacturing
today has greatly improved output tolerances but again accuracy
is usually proportional to price. Better matched cells will save
set-up and calibration time.
Have you put weights on
and off a vessel only to find the readings
change each time?
If you load cells
are not well matched then our accuracy varies by the difference
in cells.
Adjusting the pots
on the summing card is the only way to improve system
performance.
Matched cells
all respond the same so variations are mechanical attachments and not the cells.
"S" cells
do not like side loading, an alignment assembly ensures proper
pull through the cell.
A clevis and yoke on at least one end
of the cell will reduce the risk
of failure.
Long support rods also assist in reducing
errors.
