Precise
tension and commpression force measurements can be
done on limited space with the miniature load cells of
series 8431 and
8432. High precision, various measuring ranges, comfortrable
load introduction via threaded pins with external winding
and small dimensions offer a wide scope of
applications in
laboratory and production. The series is one of our
most precise
miniature load cells and at the same time quite
nonsensitive to
disturbances.
All
options, typical only for larger load cells, are
available with this
miniature series such as hermetically sealed
construction, overload
protection and borings for pressure compensation when
applied under vacuum.
The load
cell is mounted firmly on the passive side to an even surface
with the thread until stop, the active side is mounted
up to the flange at
the thread end.
The thread
part of the active side is releasable for sensors up
to measuring range
≤ 0 ... 500 N. It should be screwed into the cylinder
shaped body and fastened only by hand - do not use any
tool to do so! This
is valid also for the whole sensor mounting.

| Description |
 |
The force
to be measured is introduced via the threaded pin on the
active side and the bottom side of the cylinder shaped
sensor body. The
clinging to of the inner threading and the thread
flange and bottom side should be assured. Two stabilizing
membranes in the interior of the sensor reduce the disturbing
influences of lateral force and torque to a minimum and
guarantee a high long-term stability of the electrical
and mechanical
values.
The
network for temperature compensation is positioned on
a covered board as
a thickened part of the connecting cable.
The force
limit is the greatest force in direction of the measurement
axis that the sensor can endure if it features the overload
protection. This protection is not suitable for using
the sensor in the
overload range oftentimes, neither for sudden loads.
The load must be introduced to the center and in axial
direction. Torsion
and bending forces must be avoided.
